K-Style Hand-Drawn Graffiti Portrait

Please create a Korean-style hand-drawn graffiti illustration-style character poster based on the photos uploaded by users. It preserves the characters' true identities and overall temperament, but the overall presentation is clearly more illustrated rather than realistic transfer.

Style reference: Korean semi-realistic illustrations, vivid character sense, natural and expressive facial emotions, half-body composition, and slightly dynamic poses. Emphasizing loose, spontaneous hand-drawn lines, black ink outlines, splashes of ink, draft-like brushstrokes, visible brush textures, and a blend of soft pastel tones and ink shadows, presenting a comic-style sketch-like texture.

Don't make it a highly realistic illustration, don't make it look too photolike. It should have a more "drawn" feel, with free lines, loose edges, a slightly unfinished feel, rich hair and clothing details, overall refined but with a casual graffiti feel.

Keep the background simple, which can be pure white or light-colored paper, and freely add a few handwritten short phrases, stars, hearts, arrows, ink dots, small stickers, and other symbolic decorative elements around the figure. Feel free to use your copy and background atmosphere according to your character's temperament. The overall look should be sophisticated, light, and lively, like the popular Korean-style hand-drawn character posters on X.
