Hi Julie,
I have to say I really like it, I think you have captured the texture of his skin wonderfully, it looks really soft, just how older skin is.
The only thing that I noticed, and take this with pinch of salt because I'm not really qualified to critique, is that his shoulders seem a little low, or is it his collar where it meets the face? To me it gives the impression that he is a slimmer man with a longer neck.
