Create a cartoonish full- body illustration of a skinny, fit white man wearing a white t- shirt, a black cap flipped backward, and a backpack. His pose should be casual and relaxed, as if he's about to head out for an adventure. Emphasize his slim, athletic build, and give him a confident yet easygoing expression. Use bright, bold colors for the clothing and accessories, and keep the background simple to focus on the character's laid- back vibe
