Create an image of a fictional character named Steve, who unfortunately has a reputation for being a bit of a troublemaker. He has a carefree grin, shaggy brown hair, and is always seen wearing a threadbare jacket. His eyes sparkle mischievously and it's apparent that he might be up to no good. As a backdrop, use a graffiti-covered wall to signify his rebellious nature. Be sure not to depict any inappropriate or offensive content within the image.
