紅底人像,冷得像一張舊照片

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.

一幅暗黑都市風數字插畫,不是攝影:純色平紅背景,不加任何多餘物體或人物,一個居中人物立於中景,構圖為半身到腰部(豎版2:3或3:4,人物從膝蓋以上到頭頂佔滿七成以上畫面)。 人物與情緒:眼神冷靜、專注、帶一絲緊繃,嘴唇緊閉,沉穩剋制,不要浪漫感或可愛感。身穿黑色細條紋或純黑剪裁西裝、黑襯衫,可選黑色領帶或皮質choker項圈,銀色垂墜耳環,項鍊保持寫實比例——一根紅色發繩是整體暗色調裡唯一的點綴線索。頭髮自然垂落,只有細微飄動,整體姿態是靜態的。 呈現語言:強烈的單側定向光在臉部和身體上刻出濃重的明暗對比,紅色背景的色彩微微滲進陰影裡,呈現出棕色與深綠色的底調,搭配暖米色高光——絕不偏向粉彩、黃色或藍色。全程保持銳利對焦(不做淺景深),以乾淨的數字插畫呈現:線條利落、色塊平滑過渡、解剖結構寫實但明顯是繪製而非拍攝——帶著濃厚的東亞現代網路漫畫氣質,身形比例接近真實但臉型略微拉長。 務必避開:照片級寫實攝影、自然光、柔焦、過曝的粉彩色調、微笑或可愛的表情、浪漫或奇幻的佈景、誇張的動漫比例、過度細膩的皮膚紋理、單反級美顏打光、雜亂的背景、光澤感服裝、運動裝、卡通化的表情、多光源棚拍、全身或環境式構圖、水彩或油畫質感、走形的解剖結構。 關鍵詞:純紅背景、數字插畫、冷峻眼神、戲劇性明暗對比、現代剪裁西裝、半身構圖、銳利線條、都市氛圍、choker與項鍊、銀色配飾、東亞網路漫畫風格、嚴肅表情。
