Korean-style graffiti illustration portrait.

Based on the user's uploaded photo, create a character poster in style. Preserve the person's real identity features and overall aura, but the overall presentation should clearly lean toward illustration style rather than realistic redrawing. Style reference: Korean-style semi-realistic illustration, distinct character presence, natural and expressive facial emotions, half-body composition, slight dynamic pose. Emphasize loose, casual hand-drawn lines, black ink outlines, ink splatter, sketch-like brushstrokes, visible brush texture, and the fusion of soft pastel tones with ink shadows, presenting a comic sketch-like texture. Do not make it into a highly realistic illustration; do not let it look too much like a photo. It should have more of a "hand-drawn" feel, with free lines, loose edges, and a slightly unfinished artistic feel in some areas. Hair and clothing details should be rich, and the overall look should be both refined and have a casual graffiti atmosphere. Keep the background simple, such as , and freely add some symbolic decorative elements around the character, such as . Please freely develop the copy and background atmosphere according to the character's aura. The final effect should be high-end, light, and lively, like a Korean-style hand-drawn character poster that would go viral on X.
