[Create a premium photorealistic studio portrait collage in a 2×3 grid, featuring the same young man consistently across all six panels. Use the uploaded photo only as a facial identity reference. Keep his recognizable facial structure, natural complexion, eyes, eyebrows, nose, lips, jawline, facial hair, and overall likeness consistent, while allowing the styling to be redesigned. In every panel, show him from the chest upward with his arms comfortably crossed. Maintain the same forward-facing pose, relaxed posture, subtle confident smirk, and composed gaze throughout the series. Change the crewneck sweater and studio backdrop in each panel to create six distinct color themes: 1. Deep navy sweater with a rich blue gradient background 2. Emerald green sweater with a matching green backdrop 3. Mustard yellow sweater with a warm golden background 4. Burgundy sweater with a deep red gradient 5. Matte black sweater with a charcoal-black studio background 6. Soft white sweater with a light neutral gradient Use professional fashion-studio lighting with soft illumination from the front-left, gentle facial shadows, natural skin texture, realistic fabric detail, subtle eye catchlights, and balanced high-contrast exposure. Keep the presentation clean and symmetrical, with identical framing and pose across all six portraits. Use a luxury menswear editorial aesthetic, realistic proportions, detailed hair strands, premium textile texture, smooth gradient backgrounds, subtle vignette, shallow depth of field, and an 85mm portrait-lens appearance. Ultra-detailed, high-resolution, cinematic photography, polished but natural skin, refined color grading, crisp focus, contemporary fashion campaign quality. No text, logos, watermark, extra people, or distracting objects.]
