A sleek 3D studio portrait of a handsome young man with styled dark hair and a neat beard, leaning casually against a giant 3D YouTube play button logo sculpture on a seamless gray backdrop. 

He wears a sharp suit in a color that perfectly matches the social media logo (a vibrant crimson red suit over a black turtleneck sweater and black leather shoes). Full-body shot, confident posture with one hand in his pocket and his arm resting on the logo. Studio lighting, clean corporate graphic design, hyper-realistic 8k render. [Customization Rule: The giant 3D logo can be set to YouTube, Facebook, Instagram, or TikTok. The suit color automatically matches the brand colors, such as a royal blue suit for Facebook, or a sunset pink-purple gradient suit for Instagram.] [Reference Image Rule: If I upload a photo, preserve my exact facial features, skin tone, eye shape, and facial structure from my uploaded image while generating this 3D social media logo scene. If no photo is uploaded, generate the full scene directly.] --ar 1:1
