AI Prompts for Illustration Styles: 12 Style Sheets

AI prompts for illustration styles work best when they lock medium, palette, and bans before you ask for poses. Use them to build a reusable style sheet, five variations, and a consistency checklist so a series matches frame one. Paste only subjects and references you own or that are public domain, and avoid living-celebrity likenesses. Below are 12 copy-paste prompts plus a flagship style-sheet builder.
