Convert this image so that the man is sitting in the center of a high-back armchair in a minimal, monochromatic studio setting. Replace the current background with a seamless wall and floor in a single solid color, either deep teal, slate blue, or forest green. Dress him in a matching jacket and pants in the same color, paired with a simple white T-shirt underneath. Keep his sneakers clean and white with subtle accents matching the outfit. Retain his wristwatch as an accessory. His posture should be upright and composed, with both feet flat on the ground and his hands gently clasped in his lap. The chair should match the overall color scheme to create a seamless monochrome effect. Lighting should be soft, even, and studio-style, with minimal shadows. The final image should be ultra-high-resolution, sleek, modern, and minimalist, in the style of high-fashion portrait photography.
