Prompt: Transform this photo into a whimsical folk flat illustration with doodle elements. Preserve the original composition and characters, but simplify all details into clean colorful flat shapes with a handmade childlike feel.

The overall mood should feel warm, joyful, artistic, and charming like a modern children’s book illustration.
