红底人像,冷得像一张旧照片

A dark urban digital illustration, not a photograph: a solid flat red background with zero extra objects or people, one centered figure occupying the mid-ground in a bust-to-waist composition (vertical 2:3 or 3:4, the figure filling over 70% of the frame from above the knees to the head). Subject and mood: a cold, focused, faintly tense gaze, lips firm, calm and composed, no romance or cuteness allowed. Wearing a black pinstripe or solid black tailored suit, black shirt, optional black tie or leather choker, silver drop earrings, a necklace kept at realistic scale — a red hair tie is the one accent thread running through the otherwise dark palette. Hair flows naturally with only subtle movement, static overall pose. Rendering language: strong one-directional lighting carves deep chiaroscuro shadows across face and body, the red backdrop bleeding faintly into those shadows as brown and dark-green undertones against warm cream highlights — never shifting toward pastel, yellow or blue. Everything stays in sharp focus (no shallow depth of field), rendered as clean digital illustration: crisp linework, smooth color blocking, realistic anatomy but unmistakably painted rather than photographed — a strong East-Asian modern webtoon sensibility, near-realistic proportions with a slightly elongated face. Hard avoid: photorealistic photography, natural lighting, soft focus, overexposed pastel tones, a smiling or cute expression, romantic or fantasy staging, exaggerated anime proportions, over-detailed skin texture, DSLR beauty lighting, a busy background, glossy clothing, sportswear, cartoonish expressions, a multi-light studio setup, full-body or environmental framing, watercolor or oil-painting texture, distorted anatomy. Keywords: solid red background, digital illustration, cold gaze, dramatic chiaroscuro, modern tailored suit, bust composition, sharp linework, urban mood, choker and necklace, silver accessories, East Asian webtoon style, stern expression.

一幅暗黑都市风数字插画,不是摄影:纯色平红背景,不加任何多余物体或人物,一个居中人物立于中景,构图为半身到腰部(竖版2:3或3:4,人物从膝盖以上到头顶占满七成以上画面)。 人物与情绪:眼神冷静、专注、带一丝紧绷,嘴唇紧闭,沉稳克制,不要浪漫感或可爱感。身穿黑色细条纹或纯黑剪裁西装、黑衬衫,可选黑色领带或皮质choker项圈,银色垂坠耳环,项链保持写实比例——一根红色发绳是整体暗色调里唯一的点缀线索。头发自然垂落,只有细微飘动,整体姿态是静态的。 呈现语言:强烈的单侧定向光在脸部和身体上刻出浓重的明暗对比,红色背景的色彩微微渗进阴影里,呈现出棕色与深绿色的底调,搭配暖米色高光——绝不偏向粉彩、黄色或蓝色。全程保持锐利对焦(不做浅景深),以干净的数字插画呈现:线条利落、色块平滑过渡、解剖结构写实但明显是绘制而非拍摄——带着浓厚的东亚现代网络漫画气质,身形比例接近真实但脸型略微拉长。 务必避开:照片级写实摄影、自然光、柔焦、过曝的粉彩色调、微笑或可爱的表情、浪漫或奇幻的布景、夸张的动漫比例、过度细腻的皮肤纹理、单反级美颜打光、杂乱的背景、光泽感服装、运动装、卡通化的表情、多光源棚拍、全身或环境式构图、水彩或油画质感、走形的解剖结构。 关键词:纯红背景、数字插画、冷峻眼神、戏剧性明暗对比、现代剪裁西装、半身构图、锐利线条、都市氛围、choker与项链、银色配饰、东亚网络漫画风格、严肃表情。
