黑白矢量音乐人头像

Create a minimalist high-contrast black-and-white vector portrait on a square canvas, showing {argument name="character description" default="a long-haired bearded male indie musician"} in left-facing side profile against a solid near-black background. Use bold clean white vector outlines, thick graphic linework, and sharp negative-space shadows. The subject wears exactly 2 visible accessories: a slouchy knit beanie with a curved brim line across the forehead, and round vintage sunglasses visible as one partial circular lens on the far left edge. Show exactly 3 prominent facial/hair features that remain visible: one detailed ear, shoulder-length layered wavy hair flowing behind the neck, and a short beard along the jaw and chin. Place a large opaque vertical rectangle over the central face area, colored {argument name="overlay color" default="medium gray"}, covering most of the sunglasses, nose, mouth, and front hair; the rectangle should be centered slightly left, with straight edges and no border, like a privacy block. Keep the composition cropped tightly like a social media avatar, with the beanie nearly touching the top edge, hair reaching the lower edge, and shoulders only minimally indicated. The style should feel like an indie musician or street artist logo, suitable for an avatar, poster, T-shirt print, or brand mark. Use only {argument name="palette" default="black, white, and gray"}, no gradients except subtle flat gray variation inside the overlay, no text, no watermark, no photorealism.

创建一个极简主义的高对比度黑白矢量肖像，画布为正方形。在纯深色背景上，展示 {argument name="character description" default="一位留着长发和胡须的独立音乐人"} 的左侧侧脸。使用粗犷清晰的白色矢量轮廓、厚重的图形线条和锐利的负空间阴影。主体佩戴 2 件明显的配饰：一顶前额带有弧形帽檐线的松垮针织帽，以及一副圆形复古太阳镜（在最左侧边缘可见一个部分圆形镜片）。保留 3 个突出的面部/头发特征：一只细节丰富的耳朵、垂在颈后的肩长层次感波浪发，以及沿下颌和下巴生长的短胡须。在面部中心区域放置一个大的不透明垂直矩形，颜色为 {argument name="overlay color" default="中灰色"}，覆盖大部分太阳镜、鼻子、嘴巴和前额头发；矩形应略微偏左居中，边缘笔直且无边框，呈现出隐私遮挡块的效果。构图需紧凑，如同社交媒体头像，针织帽几乎触及顶部边缘，头发延伸至底部边缘，仅显示少量肩部线条。风格应类似于独立音乐人或街头艺术家的标志，适合用作头像、海报、T 恤印花或品牌标识。仅使用 {argument name="palette" default="黑色、白色和灰色"}，除遮挡块内部细微的平铺灰色变化外，不使用任何渐变，无文字，无水印，非写实风格。
