Lime Green Fashion Portrait

Use the subject photo as a facial identity reference. Create an ultra-realistic premium fashion portrait of a stylish adult man photographed from the chest upward against a seamless vibrant lime-green studio background. Give the man a neat short low-cut haircut with a clean natural hairline and subtle taper, with a clean-shaven face and well-groomed appearance. Pose him slightly turned at a three-quarter angle while facing toward the camera with a calm, confident expression. Dress him in a bright lime-green tailored blazer with sharp structured lapels over a fitted black high-neck turtleneck sweater. Keep the outfit minimal, modern, and fashion-forward with no necklace, no chain, and no earrings. Add stylish lime-green rounded sunglasses with dark black lenses, matching the blazer and background. Make the sunglasses feel premium and contemporary, with realistic reflections on the lenses. Use soft professional studio lighting with gentle frontal illumination, subtle rim light around the head and shoulders, realistic shadows, smooth tonal transitions, natural skin texture, and crisp facial detail. Maintain strong contrast between the vivid lime-green clothing/background and the deep black turtleneck. Frame the portrait tightly from the chest upward with the subject slightly off-center, creating a clean luxury editorial composition. Use shallow depth of field, high-end fashion photography, realistic fabric texture, balanced exposure, sharp focus, cinematic color grading, and polished magazine-quality finishing. Aspect ratio: 1:1 square portrait.
