Whimsical Folk Graffiti Art

Please transform the entire image into a single decorative folk flat illustration, incorporating graffiti elements. Using a bold and playful color palette, completely different from the original image.
Simplify all details into clean, flat shapes with a handcrafted, slightly imperfect feel, as if painted on a blank sheet of paper. The overall style should be cute, full of childlike fun, and whimsical.
