无脸男子手持饭卷素描

Create a loose fashion illustration on a clean off-white paper background: a young East Asian man with {argument name="hair color" default="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 the facial features, while the ears, jawline, neck, and hair remain partly visible. Dress him in a bold cobalt-blue sleeveless oversized vest or haori-like outer layer with sharp angular shoulders over a dark navy long-sleeve shirt, loose black wide-leg trousers, dark blue slip-on shoes with white soles, and a small black wristwatch or bracelet. Use expressive hand-drawn ink outlines, visible sketch construction lines, rough marker strokes, watercolor-like blue fills, high-contrast shadows, and minimal background detail. Keep the composition full-body, centered, with the seated legs forming a wide diagonal base; make the clothing graphic and geometric, the hand anatomy refined, and the overall mood quiet, stylish, and slightly melancholic. No text, no props other than exactly 1 rice ball and 1 wrist accessory, no detailed background.

创作一幅随性的时尚插画风格画作，主角是 {argument name="character name" default="一位韩国青年"}，他盘腿坐在纯白背景中央。他留着凌乱的短 {argument name="hair color" default="黑色"} 发，面部被刻意遮挡：在整个面部区域覆盖一层柔和的米色矩形模糊效果，使其五官不可见。他身穿一件超大廓形、棱角分明的 {argument name="outer garment color" default="鲜艳钴蓝色"} 无袖韩服风格马甲或现代礼服夹克，肩部宽大方正，内搭深海军蓝长袖衬衫，下身穿着宽松的黑色阔腿裤，脚蹬深海军蓝平底便鞋，鞋底为白色。他的姿态放松，身体略微前倾；一只手放在膝盖附近，另一只手抬至胸侧，拿着 {argument name="food item" default="一小块可见白米饭的海苔饭卷"}。运用富有表现力的黑色墨水轮廓线、可见的素描构造笔触、马克笔般的平涂色彩、水彩质感以及高级时装编辑手稿的比例。背景保持空白的灰白色，无文字，无道具，除极简的阴影外无其他投影，重点突出大胆的蓝色服装、修长的四肢以及随性忧郁的氛围。
