The hardest part of AI illustration is keeping your character looking the same across multiple pages. Here's how to solve it:

Create a detailed character description and reuse it verbatim across every illustration:

[CHARACTER BIBLE]
Main character: small brown rabbit named Pip,
round face, large expressive eyes, floppy ears,
wearing a red and white striped shirt,
children's book illustration style,
soft watercolor, white background

Pro tip: Save this exact phrase in a text file. Copy-paste it into every prompt, then add the scene details at the end.

• Same model, same settings — never switch models mid-book
• Same style keywords in every prompt
• Same aspect ratio for all illustrations
• Generate character reference sheet first — front/back/side poses for reference

The cover must grab attention at thumbnail size:

children's picture book cover,
[CHARACTER BIBLE HERE], looking directly at viewer,
big welcoming smile, colorful title space at top,
professional picture book cover design,
bright eye-catching colors, white or simple background

For the title area:

• Leave a clear band at the top or bottom for text
• Add text area at top, clear sky/space for title to your prompt
• Add the title in Canva after generating

Critical: Always add matching art style as [main character description] to keep visual coherence.
