Full-Body Studio Lifestyle Portrait

Create an ultra-realistic full-body premium lifestyle studio portrait of subject standing centered against a seamless background_color studio backdrop. He faces the camera directly with a calm neutral expression, relaxed shoulders, and both hands tucked casually into the side pockets of his shorts. Use a natural confident stance with feet about shoulder-width apart. Outfit: an oversized plain shirt_color short-sleeve crewneck T-shirt with a tiny square logo patch on the left chest, shorts_color knee-length casual shorts, and clean white low-top sneakers with white laces. Hair is short, neat, and closely cropped; no accessories, no eyewear, no facial hair. Lighting should be soft, even, high-end studio lighting with gentle shadows under the shoes and subtle falloff on the gray cyclorama floor. Composition is vertical, full body visible from head to shoes with generous negative space around the subject, realistic skin texture, accurate fabric folds, sharp focus, editorial clothing-catalog quality, minimal modern aesthetic, no text, no watermark.
