Shoot it straight on front with a 50mm natural look, moderate depth, soft even studio lighting, clean neutral colour, on a matte studio surface.
Keep the face and features lock from the reference images, blended as a natural photographic composite.
Ground it in real facts: search grounded factual, anchored to a named location, factual over aesthetic.
