Korean Graffiti Illustration Portrait

Based on the user-uploaded photo, create a character poster in {argument name="Illustration Style" default="Korean-style hand-drawn doodle illustration"}. Preserve the person's real identity features and overall vibe, but the overall rendering should lean clearly toward illustration rather than a realistic photo-to-painting conversion. Style references: Korean-style semi-realistic illustration, a vivid sense of character, natural and expressive facial emotion, half-body composition, a slight dynamic pose. Emphasize loose, spontaneous hand-drawn lines, black ink outlines, ink splatters, sketch-like brushwork, visible brush texture, and a mix of soft pastel tones with ink shading, giving it the feel of a comic sketch. Don't make it a highly realistic illustration, and don't make it look too much like a photo. It should feel more "drawn," with free-flowing lines, loose edges, a slightly unfinished feel in places, richly detailed hair and clothing, and an overall refined yet casually doodle-like quality. Keep the background simple — it can be {argument name="Background" default="a plain white or light-colored paper texture"} — and freely add a small amount of symbolic decorative elements around the person, such as {argument name="Decorative Elements" default="handwritten short phrases, stars, hearts, arrows, ink dots, small stickers"}. Feel free to design the copy and background mood based on the person's vibe. The overall result should be sophisticated, light, and lively — like the kind of Korean-style hand-drawn character poster that goes viral on X.
