Korean Hand-Drawn Character Poster

Please create a character poster based on the user's uploaded photo 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 pure white or light-colored paper texture, and freely add a small number of symbolic decorations around the character such as 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.
