Interesting photos where he's lying down - with the skin sagging away from his face (and boy, can I sympathise with the effects of gravity!) you can see the gorgeous bone structure.
He really does have an almost classically beautiful face (in terms of art). Reminds me of Jane Seymour - taken individually, her features are not perfect, but viewed as a composite, her face is gorgeous. Sean's face is the same. The canvas makes a difference, I guess.
