Korean Hand-Drawn Character Poster

Please create a character poster based on the user's uploaded photo {argument name="Illustration Style" default="Korean Style Hand-drawn Graffiti Illustration Feel"}. Retain the character's true identity and overall temperament, but the overall presentation should be clearly more illustration-oriented, not realistic and transfer-drawn. 

Style reference: Korean-style semi-realistic illustrations, distinct character sense, naturally expressive facial emotions, half-body composition, and slightly dynamic poses. Emphasizes loose, spontaneous hand-drawn lines, black ink outlines, ink splashes, sketch-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 much like a photo. It should have a more "drawn" feel—free lines, loose edges, a slight unfinished look, rich details in hair and clothing, overall refined but with a casual doodle feel. 

Keep the background simple, such as {argument name="background" default="pure white or light-colored paper texture"}, and freely add a small number of symbolic decorations around the character such as {argument name="decorative elements" default="handwritten short phrases, stars, hearts, arrows, ink dots, small stickers"}. Copy and background atmosphere should be freely based on the character's temperament. The overall look should be high-end, light, and lively, like the popular Korean-style hand-drawn character posters on X.
