Acceptance criteria

3 bans · 3 fail conditions

Check each frame against these: bans must not appear at all, and any fail condition voids the result.

Anchor

The key visual is the only anchor: paper thickness, palette, and shadow direction are set by it; a new subject must obey the same physical constraints.

Bans · prepended to the prompt by priority

  1. 01
    no forms beyond the thickness and stiffness of paperA sagging curved surface gives the trick away
  2. 02
    no metal, no glass, no mirror reflectionsReflection makes the material read as a 3d render
  3. 03
    no short hard-edged shadowsShadows must stay long and soft, or the miniature set loses its volume

Fail conditions

  • ✗
    no crease lines or cut paper edges anywhere
  • ✗
    shadow shorter than one third of the object height
  • ✗
    more than six color blocks in the frame
Pass threshold

It should read as a handmade object you could really pick up — and crease.

Style recipe

11 reusable elements

The recipe is the wording this style carries into every prompt, so you don't rewrite it.

Identity

A miniature world built from handmade paper models

Composition

Miniature diorama, seen slightly from above

Line

Physical fold edges and cut edges

Color

Warm low-saturation color blocks

Lighting

Soft studio light, long soft shadows

Material

Colored card stock, kraft paper

Texture

Fibrous feel and crease lines

Character

Naive, geometric, approachable

Atmosphere

Playful, tactile, made to be touched

Negative

photorealistic, metal, hdri reflection

Reference

Pop-up books / papercraft stop motion
