Ultra-realistic full-length portrait of a young man sitting casually on the floor in a minimalist interior setting, against a smooth beige wall. Soft warm natural light fills the room, creating gentle shadows on the floor and wall. Pose: The posture exactly follows the reference image — the man is leaning slightly backward, with his left hand resting on the floor for support, and his right elbow bent, with his right hand lightly touching his head. One knee is bent while the other leg is extended naturally. The body positioning and hand placement must match the reference. Outfit: A dark gray zip-up hoodie layered over a light gray crew-neck t-shirt, slim white pants, and clean white sneakers. Lighting: Soft, natural, warm daylight with subtle studio-like shadows for a calm, modern atmosphere. Face: Replace the person’s face with the one from the uploaded image, maintaining realistic proportions, consistent lighting, and seamless facial blending. The facial structure, expression, and direction of gaze should match the reference pose. Mood & Style: Minimalist, relaxed, photorealistic, clean modern aesthetic. High detail, full-body shot, warm color tones, cinematic softness, ultra high resolution.
