Build the illustration brief before finishing the scene
Useful book illustration workflows begin with the reading moment. Which action must the picture make clear? What does the reader already know, and what should remain a surprise? Agree the scene, viewpoint and purpose before polishing a candidate. A beautiful image can still be the wrong image for the page.
Keep approved character and setting references close to the brief. Distinguish a lasting feature from a temporary expression, costume or lighting choice. When a detail changes, record the reason rather than silently replacing the reference. This gives the author and illustrator a shared basis for reviewing the next scene.
Review the picture as part of the book
Check an illustration alongside the passage it belongs to, not only as a separate file. Consider the page turn, available space, reading direction and the details a small screen or printed spread can actually show. Add useful alternative text and review captions in context. Layout and a final proof remain important even after the artwork is approved.
Work from your own artwork, supplied references you have permission to use, or optional AI-assisted candidates. Agree ownership, permitted uses and approval responsibilities before production. Retain the approved version and its placement notes so that a later edit does not quietly bring an earlier, rejected picture back into the edition.
Make the brief useful at the drawing desk
A good brief tells the illustrator what the image must accomplish while leaving room for visual judgment. Separate the facts that cannot change from the choices that are still open. A character may need a recognizable silhouette without every composition repeating the same pose.
Check the scene before refining the surface
Identify the action, viewpoint and information the reader should discover in the picture. If the scene takes place before a character loses an object, the object should still be present. Resolve those relationships before spending time on texture, lighting or small decorative details.
Review the image where readers will see it
Inspect approved artwork beside its text and neighboring pages, not only as a large isolated file. Check the crop, text space, sequence and descriptive information. Keep the original artwork and the selected version identifiable so a later layout change does not quietly substitute an earlier candidate.
