Athletic Male Fitness Portrait

Create a 4:5 vertical portrait photography case titled "Athletic Male Fitness Portrait". Visual direction: sportswear, side rim light, natural sweat texture, healthy physique and post-training breath. Subject requirement: a real ordinary male model, no celebrity likeness, natural facial detail, restrained but strong posture. Scene and composition: the image should feel like a complete commercial or editorial portrait, not an ID photo; keep the subject clear and make the background support the human story without irrelevant clutter. Lighting: single hard light from upper-right, crisp background shadow shape, no commercial skin smoothing. Camera: 80mm lens at f/5.6, crisp geometry, skin texture, and clothing line. Color grade: neutral gray, monochrome or one accent color, restrained but strong. Keep the result realistic and photographic, with natural facial features, skin texture, hair strands, wardrobe material, environmental light, and controlled depth of field. Avoid plastic skin, over-retouching, cartoon styling, AI artifacts, malformed fingers, and displaced facial features. Unless text is explicitly required by the visual direction, include no readable text, logos, watermarks, real brand marks, or unrelated platform UI.
