产品营销 - 无脸男子手持饭卷素描

Create a loose fashion-illustration style drawing of {argument name="character name" default="a young Korean man"} sitting cross-legged on a plain white background, centered on the canvas. He has messy short {argument name="hair color" default="black"} hair and a deliberately obscured face: place a soft beige rectangular blur over the entire facial area so no facial features are visible. Dress him in an oversized, angular {argument name="outer garment color" default="vivid cobalt blue"} sleeveless hanbok-inspired vest or modern ceremonial jacket with broad squared shoulders, layered over a dark navy long-sleeve shirt, with loose black wide-leg trousers and dark navy slip-on shoes with white soles. His posture is relaxed and slightly hunched forward; one hand rests near his lap while the other hand is raised beside his chest holding {argument name="food item" default="a small piece of seaweed rice roll with white rice visible"}. Use expressive black ink contour lines, visible sketch construction strokes, marker-like flat color fills, watercolor texture, and high-fashion editorial croquis proportions. Keep the background empty off-white, no text, no props, no shadows beyond minimal grounding, and emphasize the bold blue garment, long limbs, and casual melancholy mood.
