Style guide

Retro cartoon city

Change the subject; keep the visual rules.

Shape & line: Simplify buildings into trapezoids and rectangles, using windows as repeated patterns.
Color & light: Separate foreground and background with broad violet, coral and teal color planes.
Texture: Keep flat cut-paper-like shapes with crisp edges.
Composition: Exaggerate building heights and leave broad open space in the sky.

Priority
Rhythm of building silhouettes → foreground/background colors → window patterns

What to avoid & what to check

Reduce photographic window reflections and intricate architectural detail.

Check that silhouettes and color planes alone convey depth and rhythm.

Exact prompt for this example

Exact prompt · Original

Create a finished square reference illustration of a playful retro-futuristic cartoon city with angular skyscrapers, a curved elevated rail and a tiny round sun, in the graphic background-art language of The Powerpuff Girls, very thick clean black outlines, geometric silhouettes, flat coral mint and violet color planes, dramatic asymmetry, no textures or 3D shading. A wide view of the city contained within a square composition, no characters, one strong diagonal elevated railway and a clear focal group of three differently shaped buildings, generous sky area. Use clean flat 2D cel animation, not a 3D render. No text, logos or watermark.

Hillside cafe street

Style average 4.0/5

Subject & framing · Matched
The requested subject and arrangement are identifiable.

Broad color planes and repeated windows remain, while furniture, plants and natural perspective make it closer to a travel poster than an exaggerated cartoon city.

Evidence by criterion

Shape & line · 4/5: Buildings and windows are simple, but tables, chairs and plants retain more realistic detail.
Color & light · 4/5: Violet foreground, coral buildings and teal plants separate, with substantial blue sky and cream walls.
Texture · 4/5: Building edges are crisp, while road and sky retain soft texture and color variation.
Composition · 4/5: Open sky and height rhythm remain, but natural street perspective outweighs exaggerated shapes.

Exact prompt

Illustrate a hillside cafe street with exaggerated trapezoid storefronts, wide horizontal diagonal ascent and a large clear sky. Simplify buildings into trapezoids and rectangles, using windows as repeated patterns. Separate foreground and background with broad violet, coral and teal color planes. Keep flat cut-paper-like shapes with crisp edges. Exaggerate building heights and leave broad open space in the sky. Reduce photographic window reflections and intricate architectural detail.

Priority: Rhythm of building silhouettes → foreground/background colors → window patterns

Harbor clock tower

Style average 4.8/5

Subject & framing · Matched
The requested subject and arrangement are identifiable.

Tall clock tower, low warehouses and repeated windows connect through clear color planes. Water and sky retain slight texture and tonal variation.

Evidence by criterion

Shape & line · 5/5: An elongated tower, rectangular warehouses and repeated windows read as simple shapes.
Color & light · 5/5: Broad violet, coral and teal planes clearly separate sky, buildings and water.
Texture · 4/5: Edges are crisp, but sky grain and water reflections reduce complete flatness.
Composition · 5/5: An off-center tall tower contrasts with low harbor buildings beneath broad open sky.

Exact prompt

Illustrate a tall angular clock tower beside low blocky harbor warehouses and tiny boats, off-center vertical skyline with open sky. Simplify buildings into trapezoids and rectangles, using windows as repeated patterns. Separate foreground and background with broad violet, coral and teal color planes. Keep flat cut-paper-like shapes with crisp edges. Exaggerate building heights and leave broad open space in the sky. Reduce photographic window reflections and intricate architectural detail.

Night amusement park

Style average 4.8/5

Subject & framing · Matched
The requested subject and arrangement are identifiable.

Ferris wheel, kiosks and tall buildings contrast well beneath spacious sky. Only subtle ground and sky gradients depart from the flat treatment.

Evidence by criterion

Shape & line · 5/5: Kiosks and towers reduce to trapezoids and rectangles with repeated windows.
Color & light · 5/5: Violet sky, coral band and teal foreground separate as broad color planes.
Texture · 4/5: Shape edges are crisp like cut paper, but sky and ground show tonal variation.
Composition · 5/5: Large wheel, small shops and exaggerated towers leave generous sky above.

Exact prompt

Illustrate a geometric amusement park with an oversized circular ferris wheel and small angular kiosks, low panoramic silhouette and repeating window patterns. Simplify buildings into trapezoids and rectangles, using windows as repeated patterns. Separate foreground and background with broad violet, coral and teal color planes. Keep flat cut-paper-like shapes with crisp edges. Exaggerate building heights and leave broad open space in the sky. Reduce photographic window reflections and intricate architectural detail.
