Based on the uploaded image, create a Korean-style hand-drawn doodle illustration character poster. Retain the person's real identity features and overall temperament, but the overall expression should be clearly illustrative, not a realistic conversion. Style reference: Korean semi-realistic illustration, distinct character feel, natural and expressive facial emotions, half-body composition, slight dynamic pose. Emphasize loose and spontaneous hand-drawn lines, black ink outlines, ink splashes, sketch-like brushstrokes, visible brush textures, and a mix of soft pastel colors with ink shadows, presenting a comic sketch-like texture. Do not make it a highly realistic illustration or too photo-like. It should have a stronger 'drawn' feel, with free lines, loose edges, partially unfinished details, rich hair and clothing details, overall refined but with a casual doodle vibe. Keep the background simple, pure white or light paper texture, with a few hand-written short sentences, stars, hearts, arrows, ink dots, small stickers, and other symbolic decorative elements freely added around the person. The text and background atmosphere should be freely expressed based on the person's temperament. Overall, it should be high-end, light, and dynamic, like a Korean hand-drawn character poster that would go viral on X.
