Street Graffiti Store Sign Design

Title: Generating a High-Brightness, Clean Background Street Graffiti Character Visual Around a Specific Theme: The subject's entire body or most of the body stands in a clean, high-brightness shallow field, with real photography or realistic portraits... 

Prompt: Generate a high-brightness, clean base street graffiti character visual around the specific theme: The subject's entire body or most of the body stands in a clean, high-brightness shallow field. Real or realistic personas mixed with bold deep lines, themed high-emotion color arrows, crosses, symbols, handwritten short sentences, and childish small graphics. Character clothing maintains the details of the theme material, while surrounding graffiti acts as temporary emotional markers, both surrounding the body and pressing on specific parts, creating the effect of "the subject being hijacked by sketch lines." Characters are extracted from the theme based on background, main structure, informational text, emphasis points, and textured shadows into shallow background, low-brightness theme color characters, a small amount of high-intensity theme color warning lines, and a small amount of cool-toned theme color handwritten character relationships. Bright but not clean or boring, carrying danger, humor, and improvisational creativity. Text and lines should have thickness differences, wrist marks, and misalignments; do not make them into neat illustration stickers.
