超写实 iPhone17 镜前自拍，黑色卫衣跪姿全身照

[Header] (3:4) Raw high-fidelity photograph, iPhone 17 Pro sensor simulation, diffused indoor ambient lighting, zero bokeh, SHARP focus from the foreground carpet textures to the background closet tracks, f/5.6 aperture for structural depth, subtle digital grain. [Subject & Identity Locking] Identity: Absolute preservation of Image A's specific facial geometry, focusing on the lip volume, cheekbone structure, and soft-glam aesthetic. Hair Physics: Voluminous dark chocolate textured waves, layered with frizz-free definition. The hair should cascade naturally over the shoulders and down the back, showing high-definition strand-level detail. Bio-Fidelity: Detailed skin physics including micro-pores, satin-finish hydration, and visible fine vellus hair along the jawline. Precise anatomical rendering of the hands, including realistic finger-joint articulation and a polished white manicure. Expression: Mirror-selfie aesthetic; the face is partially obscured by the technical device, capturing a focused gaze directed at the reflection. [Outfit & Physicality] Technical Description: High-performance athletic loungewear. An oversized black technical-cotton sweatshirt with a cropped silhouette. Lower Geometry: Technical micro-performance-wear shorts in matte charcoal grey, featuring a high-cut V-shape waistline and seamless construction. Textile Physics: High-tensile material-to-skin surface compression. The grey shorts must exhibit realistic physical tension lines across the gluteal proportions and proximal limb geometry. The black sweatshirt shows heavy fabric folding and realistic volume around the torso and arms. Footwear: Low-cut white cotton crew socks with a soft knit texture. Physicality: Confident self-assured posture. The body is positioned in a "torsion S-curve," kneeling on the floor with the torso rotated 180 degrees to face the mirror, highlighting the waist-to-hip ratio and symmetrical lower-body silhouette. [Pose & Composition] Geometry: Low-angle mirror-reflection framing. The subject is kneeling on a high-pile neutral-toned carpet. Framing: Vertical orientation capturing the full lower-body geometry and the upper-body rotation. Reflection Physics: Accurate rendering of the phone-to-hand contact point in the reflection, with the black smartphone held in a technical grip. [Environment & Lighting] Atmosphere: Minimalist modern bedroom setting. Interior Details: Large white sliding closet doors with vertical metallic tracks; a secondary arched mirror is visible in the reflection. Neutral white walls and a light-beige textured carpet. Lighting: Soft, top-down diffused lighting (3500K). The light source is positioned to emphasize the anatomical bust volume and the muscle definition in the legs without creating harsh shadows. Background Integrity: All background elements, including the closet doors and wall seams, must remain in sharp focus and perfectly grid-aligned. [Failure Prevention Rule]

[标题] (3:4) 原始高保真照片，iPhone 17 Pro 传感器模拟，漫射室内环境光，零散景，从前景地毯纹理到背景衣柜轨道都清晰对焦，f/5.6 光圈营造结构深度，细微的数字颗粒。 [主体与身份锁定] 身份：绝对保留 Image A 的特定面部几何结构，重点关注唇部丰满度、颧骨结构和柔和魅力美学。 发型物理：蓬松的深巧克力色波浪纹理，分层且无毛躁。头发应自然垂落在肩部和背部，展现高清晰度的发丝细节。 生物保真度：详细的皮肤物理特性，包括微孔、缎面光泽的水润感，以及沿下颌线可见的细小绒毛。精确解剖学渲染手部，包括逼真的指关节活动和抛光的白色美甲。 表情：镜面自拍美学；面部被技术设备部分遮挡，捕捉到注视反射的专注眼神。 [服装与体态] 技术描述：高性能运动休闲服。一件宽松的黑色科技棉卫衣，采用短款廓形。 下半身几何：哑光炭灰色科技微性能短裤，采用高腰 V 形腰线和无缝结构。 纺织品物理：高拉伸材料与皮肤表面的压缩。灰色短裤必须在臀部比例和近端肢体几何结构上展现逼真的物理张力线。黑色卫衣在躯干和手臂周围呈现厚重的褶皱和逼真的体积感。 鞋袜：低帮白色棉质船袜，具有柔软的针织纹理。 体态：自信从容的姿势。身体呈“扭转 S 形曲线”，跪在地板上，躯干旋转 180 度面向镜子，突出腰臀比和对称的下半身轮廓。 [姿势与构图] 几何：低角度镜面反射构图。主体跪在长绒中性色地毯上。 构图：垂直方向，捕捉完整的下半身几何结构和上半身旋转。 反射物理：准确渲染反射中手机与手部的接触点，黑色智能手机以技术握持方式握住。 [环境与照明] 氛围：极简现代卧室设置。 室内细节：大型白色推拉衣柜门，带有垂直金属轨道；反射中可见一个次要的拱形镜子。中性白色墙壁和浅米色纹理地毯。 照明：柔和的自上而下漫射照明 (3500K)。光源位置旨在强调解剖学上的胸部丰满度和腿部肌肉线条，同时不产生刺眼的阴影。 背景完整性：所有背景元素，包括衣柜门和墙壁接缝，都必须保持清晰对焦并完美网格对齐。 [故障预防规则]
