Even with a well-written scene description, an AI-generated illustration sometimes lands almost right, but not quite — the wrong time of day, an extra object in frame, or a character's expression that doesn't match the moment in your story. Here's how to fix that in the Studio without starting over.
Start from your character sheet, not a blank prompt
Every character in your book has an approved reference sheet the Studio uses on every page. If an illustration doesn't look like your character, the fix usually isn't a better one-off prompt — it's making sure the character sheet itself is approved and accurate, since every future page draws from it.
Use edits instead of full regenerations
Rather than throwing away an almost-right illustration and generating a completely new one, use the asset-edit flow: describe exactly what should change (make it nighttime, remove the object in the corner, adjust the expression), and the edit is built from your existing approved image, preserving everything you didn't ask to change.
Be specific about mood and lighting
Vague scene descriptions produce vague results. Naming the time of day, the emotional tone of the moment, and where the character's attention is directed gives the illustrator much more to work with than a general summary of the action.
Review before you approve
Nothing moves forward in your book until you approve it. Take the moment to check a new illustration against the page text and the rest of your book before locking it in — it's much easier to request one more revision now than to notice an inconsistency during final review.
Remember what's fixed for a reason
The Studio deliberately renders your title and byline text separately from cover artwork, and keeps generated art from ever automatically re-cropping an approved image. If something looks intentionally constrained, it usually is — and there's a more precise tool for what you're trying to do.
