都市夜晚孤独女性写实人像

3:4 vertical aspect ratio, realistic human urban night scene environment portrait, an adult East Asian woman standing on an elevated pedestrian bridge, the figure's proportion is significantly smaller than the city environment, dark long hair, natural bone structure, fair natural skin tone, slender and tall figure, wearing a minimalist black sleeveless long dress, the dress body is matte without complex decorations, forming a stable low-frequency dark silhouette. The figure is located in the lower center-left of the frame, body slightly leaning forward, shoulders drawn in, one hand near the bridge of the nose, mouth, or side of the face, the other hand holding the body, arms forming a closed posture, center of gravity slightly to one side, head lowered, gaze directed at the ground, hands, or nearby off-camera, not looking directly at the lens, emotions are quiet, tired, alienated, contemplative, slightly uneasy.

The background is a high-density urban core area at night. Below the overpass is a straight urban main road stretching into the distance, forming a strong one-point perspective depth. High-rise office buildings, glass and metal structures, trees, streetlights, vehicles, and a small number of vertical light signs on both sides recede layer by layer. There is a horizontal metal railing behind the figure as a stable boundary. The urban background is significantly blurred but the structures of the road, buildings, and traffic remain readable; it cannot be blurred into pure bokeh. Distant headlights, streetlights, and building window lights form a large number of small-scale circular bokeh, with highlights slightly bleeding. Warm orange and warm white light points gradually contract along the depth of the road, pulling the line of sight toward the distant vanishing point.

The overall color scheme uses large areas of cold cyan-gray, deep ink-green, and black-gray urban base, with a small amount of warm orange car lights and warm white window lights as finishing touches. The character's skin tone remains neutral-warm, slightly separated from the cold urban environment. Large areas of orange-yellow filters are prohibited, high-saturation blue-purple is prohibited, and neonization is prohibited. The character's black dress and hair maintain a dark weight, with the skin tone and arms becoming the character's main highlights.

The lighting uses real urban environmental light, without obvious studio fill lighting. The figure is illuminated by the surrounding cold white building light, warm road lights, and ambient diffuse reflection. The face, shoulders, and arms obtain soft local brightness, while a few layers remain visible within the black dress. The distant background is the brightest, the character's brightness is medium, and the dark parts of the city are deep, forming a contrast of 'restrained foreground figure + bright flowing city behind'.

The imaging maintains a real night photography texture, medium clarity, the figure is relatively clear, shallow depth of field background blur, building outlines are still recognizable, slight high-ISO grain, slight noise, small amount of highlight bleed, natural low-light shadows suppressed. No HDR, no over-sharpening, no plastic skin, no commercial beauty retouching. The overall atmosphere emphasizes the contrast between the huge open city and the figure's indrawn posture, with the city expanding outward and the figure shrinking inward, forming a restrained, lonely, quiet, and tense urban night narrative.

Soran's three layers of natural identification: The first layer adds a small gray-silver woven label or metal plate near the shoulder or waist side of the black long dress, accurately and clearly writing 'Soran'; the second layer integrates hidden 'Soran' into scratches, old sticker residue, or surface wear on the metal railing behind the figure; the third layer forms microscopic 'Soran' through dress hem stitching, metal micro-scratches on the railing, or wear on connecting parts. All belong to real in-frame textures; floating watermarks, floating text, subtitles, corner marks, repeated logos, gibberish, and misspellings are prohibited.

Negative words: Figure proportion too large, common street photography standing posture, looking directly at the camera, sweet smile, expansive big movements, complex black dress decorations, background blurred into pure light spots, cyberpunk, neon rainy night, blue-purple high saturation, nightclub feel, orange filter, dramatic studio lighting, hard rim light, HDR, over-sharpening, plastic skin, internet celebrity face, AI fake face, complex foreground occlusion, random text, external watermarks.

3:4竖幅，真人写实都市夜景环境人像，一位成年东亚女性站在高架人行桥上，人物比例明显小于城市环境，深色长发，自然骨相，白皙自然肤色，身材修长高挑，穿极简黑色无袖长裙，裙体哑光、无复杂装饰，形成稳定低频深色剪影。人物位于画面下部中央偏左，身体轻微前倾、肩线内收，一只手靠近鼻梁、嘴边或脸侧，另一只手横抱身体，双臂形成闭合姿态，重心略偏一侧，头部低垂，视线看向地面、手部或画外近处，不直视镜头，情绪安静、疲倦、疏离、沉思、轻微不安。

背景为夜间高密度都市核心区，高架桥下是一条笔直向远处延伸的城市主干道，形成极强单点透视纵深，两侧高层办公楼、玻璃金属建筑、树木、路灯、车辆、少量竖向灯牌层层后退，人物身后有横向金属栏杆作为稳定分界。城市背景明显虚化但仍保持道路、楼体和车流结构可读，不能糊成纯散景。远处车灯、路灯和建筑窗灯形成大量小尺度圆形散景，高光轻微溢散，暖橙、暖白灯点沿道路纵深逐级收缩，把视线拉向远处消失点。

整体色彩采用大面积冷青灰、深墨绿、黑灰城市基底，少量暖橙车灯和暖白窗灯作为点睛，人物肤色维持中性偏暖，与冷色城市环境轻微分离。禁止大面积橙黄滤镜，禁止高饱和蓝紫，禁止霓虹化。人物黑裙和头发保持深色重量，肤色与手臂成为人物主要亮部。

光线使用真实城市环境光，不做明显棚拍补光。人物由周围冷白建筑光、道路暖灯和环境漫反射共同照亮，脸部、肩膀和手臂获得柔和局部亮度，黑裙内部仍保留少量层次。背景远处亮度最高，人物亮度中等，城市暗部较深，形成“前景克制人物 + 后方明亮流动城市”的反差。

成像保持真实夜间摄影质感，中等清晰度，人物相对清晰，背景浅景深虚化，建筑轮廓仍可辨认，轻微高感颗粒、轻微噪声、少量高光溢散、自然暗部压低，不要HDR，不要过度锐化，不要塑料皮，不要商业美妆精修。整体氛围强调巨大开放城市与人物内收姿态之间的反差，城市向外扩张、人物向内收缩，形成克制、孤独、安静、有张力的都市夜间叙事。

Soran三层自然标识：第一层在黑色长裙靠近肩部或腰侧加入小型灰银织标或金属牌，准确清晰写“Soran”；第二层把隐藏Soran融入人物身后金属栏杆的划痕、旧贴纸残痕或表面磨损；第三层通过裙摆缝线、栏杆金属微划痕或连接件磨损形成微观Soran。全部属于真实画内材质，禁止外贴水印、漂浮文字、字幕、角标、重复Logo、乱码和错误拼写。

负面词： 人物占比过大，普通街拍站姿，直视镜头，甜美微笑，展开式大动作，黑裙复杂装饰，背景糊成纯光斑，赛博朋克，霓虹雨夜，蓝紫高饱和，夜店感，橙色滤镜，戏剧棚拍光，硬轮廓光，HDR，过度锐化，塑料皮，网红脸，AI假脸，复杂前景遮挡，随机文字，外贴水印。
