Cinematic Actor Portrait Transformation

Using the provided reference image as the base portrait, transform the subject into a polished cinematic portrait of {argument name="target actor" default="Robert Downey Jr."}. Keep the same chest-up studio composition, direct eye contact, white sweatshirt, moody blue background, and warm orange side/rim lighting. Change the facial identity, haircut, and facial hair to match the target actor: shorter styled hair, trimmed goatee/mustache, sharper features, and a more refined naturally realistic look. Maintain realistic skin texture, professional portrait lighting, shallow depth of field, and high-end editorial finish. Do not add text, props, logos, or extra people.
