Korean Graffiti Illustration Portrait

Based on the user-uploaded photo, create a 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 pure white or light-colored paper texture, and freely add a few symbolic decorative elements around the character like handwritten short phrases, stars, hearts, arrows, ink dots, small stickers. Please 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.
