ภาพร่างแฟชั่นเสื้อกั๊กสีน้ำเงินโคบอลต์

Loose fashion illustration on a clean off-white paper background: a young East Asian man with [messy black hair] sits cross-legged in a relaxed pose, body angled slightly left, holding a half-eaten triangular rice ball in his raised right hand. His face is intentionally obscured by a soft rectangular blur centered over his facial features, while ears, jawline, neck, and hair remain partly visible. Attire: - Bold cobalt-blue sleeveless oversized vest or haori-like outer layer with sharp angular shoulders - Dark navy long-sleeve shirt underneath - Loose black wide-leg trousers - Dark blue slip-on shoes with white soles - Small black wristwatch or bracelet on his wrist Composition & Style: - Centered full-body composition with seated legs creating a wide diagonal base - Expressive hand-drawn ink outlines, visible sketch construction lines, and rough marker strokes - Watercolor-like blue fills and high-contrast shadows - Graphic, geometric clothing shapes and refined hand anatomy - Quiet, stylish, slightly melancholic mood - Minimal background detail, no text, no props other than exactly 1 rice ball and 1 wrist accessory
