Detailed result requirements

Required inputs

Hand-drawn or digital sketch + allowed range of modifications → Keep the composition and add colors and details → Complete the illustration in the current single picture

Input quality

Text/sketch, audience age, theme, composition, color palette, proportion, reference style and prohibited elements.

Composition

No universal public standard is available. Check the requirements of the platform or service you will use.

Output aspect ratio

Set the output canvas from the selected platform placement or production template, not from a reference image. Choose the option that matches this request: Complete illustration working canvas — 4:5 (recommended). Use a different ratio only when a verified placement or production template requires it. If the platform does not require a fixed aspect ratio, use 4:5 as the recommended working canvas for complete illustration. Compose the subject with appropriate breathing room. Create one aspect-ratio-specific deliverable per request; generate each additional placement as a separate output. Recompose for the selected ratio while preserving the complete subject, all text, and every required safe area. Never stretch the subject or treat cropping important content as adaptation.

What stays unchanged

The sketch has identified the main morphological and narrative information.
