Create a highly realistic vertical 4:5 close-up summer fashion portrait of a young adult man using the uploaded photo as the visual identity reference; maintain consistent facial appearance, structure, eyes, eyebrows, nose, lips, jawline, skin tone, age, grooming, facial hair if present, proportions, and recognizable features. Frame him from the chest upward against a completely clear vivid light-blue sky. He wears a beige/tan oversized bucket hat with a distressed frayed brim and subtle unreadable embroidery, black rectangular sunglasses with dark tinted lenses, and a fitted black sleeveless top. Preserve the reference hair color and natural masculine hairstyle, slightly tousled by a light breeze. His head is turned slightly aside while remaining partly toward camera; one hand gently touches the hat brim, with understated rings if suitable. Calm confident slightly serious expression. Strong golden summer sunlight, warm skin highlights, realistic soft shadows, 50mm lens, f/2.0, shallow depth of field, natural pores, realistic hair and fabric, subtle film grain, no text, logos, branding, or watermark. STRICT MASCULINE LOCK: preserve original grooming and facial hair, masculine styling only, no feminine elements, makeup, accessories or poses.
