Vladimir LegkostupovプロンプトTransform this portrait into a professional LinkedIn headshot with the following specifications: Create a studio-quality portrait showing head and shoulders, with the face centered and occupying about 55% of the frame. The subject should be wearing a plain white t-shirt without any logos or patterns instead of the current burgundy shirt. Maintain all distinctive facial features including the light beard, mustache, eye color, facial structure, and hairstyle exactly as they are. The person should have a natural, slight smile and direct eye contact with the camera. Replace the background with a soft, light gray studio background with subtle blur. Ensure professional studio lighting that is even and flattering. Keep the composition classic for business portraits with appropriate headroom above the head and visible shoulders. Preserve the person's natural appearance and individuality completely - no makeup or accessories should be added.
