Korean hand-drawn graffiti character poster AI Image Prompt

Based on the user-uploaded photo, create a {argument name="illustration style" default="Korean-style hand-drawn graffiti illustration"} character poster. Retain the person's real identity features and overall temperament, but the overall presentation should be clearly slanted towards illustration rather than realistic redrawing. Style Reference: Korean semi-realistic illustration, distinct character feel, natural and expressive facial emotions, half-body composition, slight dynamic poses. Emphasize loose, spontaneous hand-drawn lines, black ink outlines, ink splatters, sketch-like strokes, visible brush textures, and a blend of soft pastel tones and ink shadows, presenting a manga-sketch-like texture. Do not make it a highly realistic illustration; do not make it look too much like a photo. It should have more of a "drawn" feel, with free lines, loose edges, and partial areas feeling slightly unfinished. Hair and clothing details should be rich, and the overall look should be exquisite yet with a casual graffiti vibe. Keep the background simple, such as {argument name="background" default="pure white or light-colored paper texture"}, and freely add a few symbolic decorative elements around the character like {argument name="decorative elements" default="handwritten short phrases, stars, hearts, arrows, ink dots, small stickers"}. Let the copywriting and background atmosphere develop freely based on the character's temperament. The overall result should be high-end, light, and agile, like a Korean-style hand-drawn character poster that would go viral on X.
