Separate identity from scene
A strong character prompt has two layers: identity details that stay fixed, and scene details that can change from page to page.
- Identity: age, face shape, signature outfit, emotional tone.
- Scene: location, action, weather, supporting props.
- Guardrail: what should only change when explicitly requested.
Keep the reading age in mind
Children’s book art is not just about style. The complexity, contrast, and emotional intensity should match the age band of the reader.
Reuse the template, not the full prompt blob
The template is there to protect the character, not to freeze creativity. Keep the stable facts reusable, then write each page as a fresh beat.
