水墨风武士肖像

创作一张黑白分明的水墨插画，主体为 {argument name="character type" default="狂野的武士式浪人"} 的半身像，背景为纯白，采用戏剧性的漫画毛笔风格，结合粗犷的排线、厚重的黑色阴影、飞溅的墨点以及极具表现力的刮擦线条。人物身着宽松、深色且破烂的和服长袍，领口深开，露出修长的筋骨分明的脖颈和上胸部，衣物边缘破损，一侧带有隐约的磨损花纹。头部中央被一个巨大的 {argument name="face obscuration" default="中灰色方形遮挡块"} 覆盖，但杂乱且修长的 {argument name="hair color" default="黑色"} 发丝从遮挡块周围向外迸发，形成交织的弧线，横跨图像上半部分。在人物周围添加 4 个黑色飞鸟剪影：左上方有一只展开双翼的大乌鸦或渡鸦，左下方有一只小鸟，左侧中部有一个细小的羽毛状黑色形状，右侧边缘有一只较小的乌鸦剪影。采用高对比度、单色水墨能量、硬核青年漫画氛围，除灰度外无其他颜色，无文字，无边框，肖像构图，体现强烈的风感与动态，服装和颈部具有细腻的墨迹质感，背景保留极简的白色负空间。

Create a stark black-and-white ink illustration of a {argument name="character type" default="wild samurai-like wanderer"} shown from the chest up against a blank white background, in a dramatic manga brush-pen style with rough crosshatching, heavy black shadows, splattered ink, and expressive scratchy linework. The figure wears a loose, dark, tattered kimono robe with a deep open collar exposing a long sinewy neck and upper chest, with ragged fabric edges and subtle worn floral markings on one side. The head is mostly covered by a large centered {argument name="face obscuration" default="flat medium-gray square censor block"}, but chaotic long {argument name="hair color" default="black"} hair bursts outward around it in many thin windblown strands, forming tangled arcs across the upper half of the image. Add exactly 4 black bird silhouettes around the figure: one large crow or raven flying in the upper left with wings spread, one small bird flying at lower left, one tiny feather-like black shape near the left middle, and one smaller crow silhouette at the right edge. Use high contrast, monochrome sumi-e energy, gritty seinen manga mood, no color except grayscale, no text, no frame, portrait composition, intense wind and motion, detailed ink texture on clothing and neck, minimal white negative space background.
