In a linen shirt

Create a portrait, without altering the facial features. Cinematic hyperrealistic close-up portrait, 8k. A man sits relaxed, one hand raised behind his head, his back leaning against a wall. He wears a light unbuttoned linen shirt, with vibrant folds visible in the side sunlight. Harsh top-side light, Rembrandt lighting: brightly illuminated near side of the face, cheekbones, nose, forehead; a triangle of light on the far cheek. Deep shadows under the cheekbones and chin, on the neck. An athletic build man.
