Graffiti Folk Fantasy Illustration

Transform this photo into a fantasy folk flat illustration with graffiti elements. The original composition and figures are preserved, but all details are simplified into clean, colorful, flat shapes with a playful handmade feel. Use soft and vibrant colors, rosy cheeks, playful line art, adorable decorative symbols, flowers, birds, whirlpools, and warm urban background details. The overall atmosphere should be like the illustrations in modern children's books—warm, joyful, artistic, and full of charm.
