A character's colors and objects can become the architecture of a world. These six prompt sets move from a portrait to a miniature setting inside an open book, then into a picture-book scene with a story seed to explore.

Start with a character, then build the book

Choose a portrait and generate it first. For the book prompt, use the same written palette and symbols, or attach the portrait as a motif reference; for the scene, attach the portrait for identity and optionally the book image for setting. Attachments can help, but identity and details may drift. Use an original character or an image you have permission to use.

These examples were generated in ChatGPT and reviewed. The book worlds crop the books despite instructions, and the picture-book scenes drift toward detailed painting rather than the requested simplified pastel treatment.

Reusable world-in-a-book template

Keep the book visible and translate the character's palette and two symbols into a few deliberate features. The person need not appear in the miniature world.

Reusable templateWorld in a book3:4

Create a vertical 3:4 fantasy illustration of an open [book material and color] book on [surface], viewed from a slightly elevated three-quarter angle. Keep both covers, the spine, and page edges visible. Inside the pages, build a contained miniature [world type] as a physical diorama. Use [three character colors] and transform [two character symbols or objects] into architecture, ornaments, or landscape details. If a character reference is attached, use it for palette and motifs; otherwise use the written details. Do not depict the character in the book. Include [one focal landmark], [two supporting details], and [one mysterious detail]. Use [materials] and [lighting] to create a [mood] atmosphere. Give the focal landmark room to read; keep the surrounding room quiet. No readable text, logos, or watermark.

Mira and the moonlit forest library

Mira tends the books that the forest refuses to forget. When a key appears in her pocket, the library’s locked door begins to whisper a story she has never read.

Character portrait

Character portrait3:4

Create a vertical 3:4 fantasy character portrait of Mira, an original forest librarian: a young adult woman with brown skin, short curly black hair, a deep green cloak, a gold leaf clasp, and a small silver key. Show a clear three-quarter view from head to knees, with the signature objects visible. Use deep green, silver, and gold as the dominant palette. Gentle painterly storybook concept art, simple background, soft directional light, readable silhouette and natural anatomy. No other characters, text, logo, or watermark.

Book world

The generated book is cropped at the frame edge, despite the full-book instruction; a second attempt also cropped it.

Moonlit miniature forest library inside a partially cropped open book
Book world3:4

Create a 3:4 vertical fantasy illustration of an old open book resting on a dark wooden desk, viewed from a slightly elevated three-quarter angle. Inside its pages, a miniature moonlit forest rises like a carefully made paper-and-wood diorama. The open book remains fully visible, with the landscape contained within its covers. Character inspiration: forest librarian. Use deep green, silver, and gold and a leaf clasp and a silver key from the supplied character reference, if attached, or from this written brief. Let these details shape the architecture and decorations; do not depict the character unless requested. A narrow winding path leads through silver-barked trees to a tiny library built into a hollow trunk. Warm light glows through its windows. Small books hang from branches, mushrooms mark the path, and a stream reflects the moon. A single closed door at the back of the library hints at a secret. The book has a deep green cloth cover, worn gold corners, and deckled paper. Moonlight falls from the upper left; the library provides a softer, warm light. Layered paper foliage, carved-wood textures, fine details and generous dark space around the book. No readable text, labels, watermark, or additional books outside the diorama.

Picture-book scene

The scene retains Mira's identity, but both attempts drifted toward detailed painting rather than the requested simplified oil-pastel style.

Mira kneeling with a key beside the forest library door
Picture-book scene3:4

Create a vertical 3:4 picture-book illustration of Mira, the same forest librarian: a young adult woman with brown skin, short curly black hair, a deep green cloak, a gold leaf clasp, and a small silver key. If attached, use the portrait as the character identity reference and the book-world image as a setting reference; otherwise follow this description. Preserve the hair, skin tone, clothing, and signature objects. Scene: Mira kneels beside the hollow-tree library, holding her key toward a closed door while a moth rests on a book. Use deep green, silver, and gold and one dominant decorative motif: large silver leaves. Render in oil pastel and colored pencil on softly textured paper, with broad color shapes, selective texture, clean facial features, and visible negative space. One coherent scene, no panels, text, logo, or watermark.

Nerin and the city beneath the tide

Nerin maps the drowned city for travelers who have forgotten its name. A broken chain leads him to a dry throne room, where something has escaped without disturbing the water.

Character portrait

Nerin the sea mage in a teal coat with braids and a shell brooch
Character portrait3:4

Create a vertical 3:4 fantasy character portrait of Nerin, an original sea mage: an adult man with deep brown skin, long dark teal braids, a pearl earring, and a blue-green coat fastened with a brass shell brooch. Show a clear three-quarter view from head to knees, with the signature objects visible. Use blue-green, pearl white, and aged brass as the dominant palette. Gentle painterly storybook concept art, simple background, soft directional light, readable silhouette and natural anatomy. No other characters, text, logo, or watermark.

Book world

The book is cropped at the frame edges in both attempts, despite the visible-cover instruction.

Miniature underwater city in a partially cropped open book
Book world3:4

Create a 3:4 vertical fantasy illustration of an open leather-bound book on a weathered stone table. A miniature underwater city fills the open pages like a glass-sided diorama; the book's cover and page edges remain visible around it. View the scene from a slightly elevated three-quarter angle. Draw the palette and ornaments from sea mage, blue-green, pearl white, and aged brass, and a shell brooch and a broken chain. If a character reference image is attached, use it for visual motifs and color, not as a figure to place in the city. Within the book, slender towers and bridges rise among coral gardens. Small fish weave through an arched marketplace. At the center, a translucent dome shelters a dry, abandoned throne room; a broken chain trails from its entrance. An ancient lighthouse stands at the edge of the pages, its beam cutting through blue-green water. Use translucent glass, pearl, aged brass, and pale stone. Light filters down from above with gentle caustic patterns, while the lighthouse gives a small warm focal point. Keep the city clearly readable and the water contained within the book. No readable text, logos, watermark, or extra hands.

Picture-book scene

Nerin remains recognizable, but the scene is more detailed than the requested simplified picture-book style, even after a second attempt.

Nerin swimming beside coral and a broken chain toward a domed throne room
Picture-book scene3:4

Create a vertical 3:4 picture-book illustration of Nerin, the same sea mage: an adult man with deep brown skin, long dark teal braids, a pearl earring, and a blue-green coat fastened with a brass shell brooch. If attached, use the portrait as the character identity reference and the book-world image as a setting reference; otherwise follow this description. Preserve the hair, skin tone, clothing, and signature objects. Scene: Nerin swims beside a coral arch, studying a broken chain leading toward a glass-domed throne room. Use blue-green, pearl white, and aged brass and one dominant decorative motif: broad coral fans. Render in oil pastel and colored pencil on softly textured paper, with broad color shapes, selective texture, clean facial features, and visible negative space. One coherent scene, no panels, text, logo, or watermark.

Ivo and the floating-island observatory

Ivo charts the routes between islands from a dawn-lit observatory. One morning the atlas shows a fourth island, but every telescope points to empty sky.

Character portrait

Ivo the astronomer with white hair, round glasses and a crescent-moon coat
Character portrait3:4

Create a vertical 3:4 fantasy character portrait of Ivo, an original sky astronomer: an adult person with warm brown skin, short white hair, round brass spectacles, and a navy coat embroidered with a crescent moon. Show a clear three-quarter view from head to knees, with the signature objects visible. Use navy, pale cream, and brass as the dominant palette. Gentle painterly storybook concept art, simple background, soft directional light, readable silhouette and natural anatomy. No other characters, text, logo, or watermark.

Book world

Both attempts cropped the atlas at the frame edges, despite the instruction to show the whole book.

Floating observatory islands above a partially cropped open atlas
Book world3:4

Create a 3:4 vertical fantasy image of a large open atlas on a quiet worktable. Above its pages, a small cluster of floating islands forms one contained miniature world. The full book, its spine, and both page edges must remain visible. Show the scene from a three-quarter angle with enough space above the book for the islands. Take the visual language from sky astronomer: navy, pale cream, and brass and a crescent moon and a compass rose. If a character reference is attached, translate its motifs into the landscape and instruments instead of reproducing the person. The largest island carries a brass observatory with a retractable dome and a telescope aimed at a tiny crescent moon. Rope bridges connect it to an orchard island and a windmill island. Wisps of cloud drift beneath the bridges. On the atlas page below, a compass rose points toward an empty space where a fourth island might once have been. Use aged paper, pale stone, brushed brass, and soft cloud. Dawn light catches the observatory dome; the surrounding room stays muted. A clear visual hierarchy: book first, observatory second, smaller islands third. No readable lettering, watermark, or modern machinery.

Picture-book scene

Ivo remains recognizable, but the scene is more detailed than the requested simplified pastel style after two attempts.

Picture-book scene3:4

Create a vertical 3:4 picture-book illustration of Ivo, the same sky astronomer: an adult person with warm brown skin, short white hair, round brass spectacles, and a navy coat embroidered with a crescent moon. If attached, use the portrait as the character identity reference and the book-world image as a setting reference; otherwise follow this description. Preserve the hair, skin tone, clothing, and signature objects. Scene: Ivo leans over an atlas on a floating island and points to an empty space beyond the rope bridge. Use navy, pale cream, and brass and one dominant decorative motif: large crescent moons. Render in oil pastel and colored pencil on softly textured paper, with broad color shapes, selective texture, clean facial features, and visible negative space. One coherent scene, no panels, text, logo, or watermark.

Elowen and the winter dragon's garden

Elowen cares for a garden that should not survive the winter. Its only flowering tree closes whenever the dragon wakes, and the tracks in the snow are not hers.

Character portrait

Character portrait3:4

Create a vertical 3:4 fantasy character portrait of Elowen, an original winter dragon keeper: an adult woman with freckled light brown skin, a long auburn braid, a pale blue wool coat, a snowflake pin, and a copper watering can. Show a clear three-quarter view from head to knees, with the signature objects visible. Use pale blue, snow white, and copper as the dominant palette. Gentle painterly storybook concept art, simple background, soft directional light, readable silhouette and natural anatomy. No other characters, text, logo, or watermark.

Book world

Both attempts cropped the book at the frame edge, despite the full-book instruction.

Sleeping dragon and winter greenhouse inside a partially cropped book
Book world3:4

Create a 3:4 vertical fantasy illustration of a thick open storybook on a pale stone windowsill. Inside the pages is a miniature winter garden, contained within the book's covers and viewed from a slightly elevated three-quarter angle. Keep the whole open book visible. Build the garden around winter dragon keeper, pale blue, snow white, and copper, and a snowflake pin and a watering can. An attached character image, if present, supplies color and motifs; do not add a portrait or a full-sized person. A small sleeping dragon curls around a ruined greenhouse. Inside its cracked glass roof, one flowering tree glows faintly despite the snow. A frozen pond, a stone bench, and a trail of small footprints lead from the edge of the page to the greenhouse door. Make the dragon's silhouette clear and keep it small enough that the garden remains the main subject. Use frosted glass, powdery snow, weathered stone, and delicate paper-like branches. Cool window light falls across the book; the tree adds a restrained warm glow. Quiet, protective mood, detailed but not crowded. No readable text, watermark, or extra dragons.

Picture-book scene

Elowen remains recognizable, but both attempts are more realistic and detailed than the requested oil-pastel treatment.

Elowen setting a copper watering can near a flowering tree as a dragon sleeps
Picture-book scene3:4

Create a vertical 3:4 picture-book illustration of Elowen, the same winter dragon keeper: an adult woman with freckled light brown skin, a long auburn braid, a pale blue wool coat, a snowflake pin, and a copper watering can. If attached, use the portrait as the character identity reference and the book-world image as a setting reference; otherwise follow this description. Preserve the hair, skin tone, clothing, and signature objects. Scene: Elowen sets a copper watering can beside a flowering tree in a cracked greenhouse while a small dragon sleeps outside. Use pale blue, snow white, and copper and one dominant decorative motif: large snowflakes. Render in oil pastel and colored pencil on softly textured paper, with broad color shapes, selective texture, clean facial features, and visible negative space. One coherent scene, no panels, text, logo, or watermark.

Sahir and the desert clockwork caravan

Sahir keeps the caravan moving even though its tallest clock stopped years ago. When its hands twitch, the walking houses turn toward a half-buried arch no map records.

Character portrait

Character portrait3:4

Create a vertical 3:4 fantasy character portrait of Sahir, an original caravan clockmaker: an adult man with warm brown skin, close-cropped black hair, a rust-red scarf, a sand-colored coat, and a brass gear pendant. Show a clear three-quarter view from head to knees, with the signature objects visible. Use sand, rust red, and brass as the dominant palette. Gentle painterly storybook concept art, simple background, soft directional light, readable silhouette and natural anatomy. No other characters, text, logo, or watermark.

Book world

Both attempts cropped the book and added clock numerals, despite instructions to avoid both.

Three clockwork walking houses in a partially cropped desert journal
Book world3:4

Create a 3:4 vertical fantasy illustration of an open travel journal on a sandstone surface. Inside the pages, a miniature desert landscape contains a slow-moving clockwork caravan. The book is the frame for the world: show both covers, the center fold, and the curled page edges from a slightly elevated angle. Use caravan clockmaker, sand, rust red, and brass, and a gear pendant and a stopped clock to guide the caravan's flags, ornament and palette. If a character reference image is attached, borrow its motifs rather than placing the character in the scene. Three mechanical walking houses cross dunes toward a small oasis. Each has brass legs, fabric awnings, and windows lit from within. The tallest house carries a stopped clock. Tiny tracks curve behind the caravan, and a half-buried stone arch stands near the edge of the book. Warm late-afternoon light, long shadows, weathered brass, woven cloth, and fine sand. Make the caravan readable as three distinct silhouettes without filling every space with detail. No readable text, numbers on the clock, watermark, or branded symbols.

Picture-book scene

Sahir remains recognizable, but both attempts are more detailed than the requested simplified pastel style.

Picture-book scene3:4

Create a vertical 3:4 picture-book illustration of Sahir, the same caravan clockmaker: an adult man with warm brown skin, close-cropped black hair, a rust-red scarf, a sand-colored coat, and a brass gear pendant. If attached, use the portrait as the character identity reference and the book-world image as a setting reference; otherwise follow this description. Preserve the hair, skin tone, clothing, and signature objects. Scene: Sahir stands on a dune holding a small gear while three walking houses approach an oasis. Use sand, rust red, and brass and one dominant decorative motif: large curved dunes. Render in oil pastel and colored pencil on softly textured paper, with broad color shapes, selective texture, clean facial features, and visible negative space. One coherent scene, no panels, text, logo, or watermark.

Luma and the lantern festival of the forgotten city

Luma guides forgotten memories through the city’s lantern festival. Tonight a boat waits at an empty landing, and the only dark window belongs to someone she cannot remember.

Character portrait

Character portrait3:4

Create a vertical 3:4 fantasy character portrait of Luma, an original keeper of memories: an adult woman with dark brown skin, a silver-streaked black bob, an indigo coat, a paper-boat charm, and an amber lantern. Show a clear three-quarter view from head to knees, with the signature objects visible. Use indigo, amber, and silver as the dominant palette. Gentle painterly storybook concept art, simple background, soft directional light, readable silhouette and natural anatomy. No other characters, text, logo, or watermark.

Book world

Both attempts cropped the book at the frame edge, despite the full-book instruction.

Lantern-lit miniature canal city inside a partially cropped book
Book world3:4

Create a 3:4 vertical fantasy illustration of an open, indigo-bound book on a dark tabletop. A miniature canal city unfolds from its pages at twilight. Keep the complete book visible from a slightly elevated three-quarter angle; the buildings and water should feel physically contained within the open covers. Take inspiration from keeper of memories, indigo, amber, and silver, and a paper-boat charm and a lantern. If an original character image is attached, translate its visual motifs into lantern shapes, roof ornaments, and textiles; do not create a character portrait. A canal curves between narrow old houses, crossed by a single arched bridge. Lanterns hang over the water and reflect in it. One small boat waits at an empty landing, while a single unlit window stands among the warm windows of the city. Paper boats gather beneath the bridge as though carrying messages. Use folded-paper architecture, dark lacquered wood, translucent lantern paper, and gentle watercolor-like reflections. Warm lantern light contrasts with the blue evening; keep the unlit window visible but subtle. No readable text, watermark, modern signage, or crowds.

Picture-book scene

Luma remains recognizable, but the saved scene is more detailed than the requested pastel style. A retry was interrupted when the browser closed.

Luma holding a lantern over paper boats on a canal bridge
Picture-book scene3:4

Create a vertical 3:4 picture-book illustration of Luma, the same keeper of memories: an adult woman with dark brown skin, a silver-streaked black bob, an indigo coat, a paper-boat charm, and an amber lantern. If attached, use the portrait as the character identity reference and the book-world image as a setting reference; otherwise follow this description. Preserve the hair, skin tone, clothing, and signature objects. Scene: Luma waits on a canal bridge holding an amber lantern above a cluster of paper boats, watching one dark window. Use indigo, amber, and silver and one dominant decorative motif: large lantern shapes. Render in oil pastel and colored pencil on softly textured paper, with broad color shapes, selective texture, clean facial features, and visible negative space. One coherent scene, no panels, text, logo, or watermark.

The space and creature book worlds set repeats this format with corrected book framing and a painterly scene style that the model follows more reliably.

The miniature-book approach draws on FufuCreates’ character-world grimoire; the picture-book treatment draws on their oil-pastel template. Their world-in-a-bottle uses a different container and places the character outside it. The half-chibi adventure cover and character instruction manual explore game art and personality, while HeyAbhishek’s storyboard workflow pairs character design with sequential shots. This page focuses instead on a portrait, a book-bound world, and one illustrated moment.

For visual continuity, see GPT Image character sheets; for another oil-pastel example, see art styles and media. The Nano Banana character-design guide covers character concepts in another tool, while Midjourney fantasy worlds covers broader environments. To track story facts rather than image likeness, use the character bible and world-building prompts.
