Overview
A reusable prompt template for generating watercolor and colored pencil style children's book illustrations using GPT Image, featuring specific texture, composition, and character constraints.
The prompt
| 1 | Hand-drawn children's picture book illustration, traditional media texture. The base layer consists of large blocks of watercolor and gouache, where uneven water tones, brush directions, and pigment sedimentation are visible within the color blocks; edges have water stains, and color blocks overlap semi-transparently. The upper layer uses colored pencils for lines and hatching, with line colors matching the fill colors (not ink lines or dark outlines), varying thickness, slightly shaky, many shapes left unoutlined, textures represented by hand-drawn parallel pencil lines. The image is flat and decorative, without linear perspective, depth achieved only through layered occlusion of color blocks and cooling/darkening in the distance. No unified light source, no volumetric shadows; objects have only small contact shadows drawn with colored pencil hatching. Background sprinkled with fine white and light-colored granular dots. Dark colors use indigo or deep purple, never pure black. |
