[GPT-image2 Structural Prompt: {argument name="主题" default="The Dark Godfather"}] ### 1. Identity Transformation (核心人像迁移) - Base Identity: Take the facial structure from [Reference Image]. - Modifications: Age the face by {argument name="年龄增加" default="30 years"}, adding deep-seated wisdom lines and weathered, leathery skin texture. Maintain the stoic, unshakable gaze of a high-status leader. ### 2. Lighting Architecture (顶光与阴影结构 - 关键) - Light Source: A single, harsh Vertical Top-Lighting (垂直顶光) from directly overhead. - Shadow Mapping: This lighting must create cavernous shadows in the eye sockets, making the eyes almost invisible in mystery.

He is slowly and rhythmically stroking a {argument name="宠物" default="dark, sleek cat"} on his lap. - Foreground: Focus on the contrast between the weathered, powerful hand and the soft fur of the cat. - Background: A pitch-black, minimalist study. Only a faint, out-of-focus silhouette of a mahogany desk is visible. - Camera: 85mm lens, f/1.8, medium shot, slight low-angle perspective. ### 4. Color & Texture (色彩与质感) - Palette: Desaturated color grading. Deep tobacco browns, obsidian blacks, and sharp amber highlights (#B08D6A / #1A120B). - Texture: 35mm film grain, Subsurface Scattering (SSS) for realistic skin highlights, PBR texture mapping (no plastic feel). ### 5.
