Create an 8K, 9:16 slightly zoomed-in portrait of a man based on a photo reference. He is facing the camera with a subtle, relaxed smile, looking handsome, stylish, and photogenic, wearing a modern street casual outfit: a stylish sweatshirt paired with slim-fit joggers and Nike Jordan sneakers, youthful yet age-appropriate. His hair is messy with a pronounced fringe, soft, voluminous, and tousled, makeup minimal or natural. In front of him is a small table with a beautifully decorated birthday cake with “30” candles. Background: luxury birthday studio with balloons, banners, fairy lights, and festive decorations. Pose him dynamically: leaning back slightly in the chair, one hand resting casually on his knee, the other hand near the cake, or arms relaxed, showing a confident, stylish stance, all in a single composition. Keep his face exactly as in the reference, slim body, radiating handsome, stylish, playful, and joyous birthday vibes.
