Hmmmm.... Very Woody Allen-esque. I'd like to see a bit more DoF and less reflection on the glasses. You need to consider where you place your lights as well; the catchlights are in the dead centre of his pupils, which gives him sort of an odd, appaerance if you look closely. All of those are relativley minor points; the lighting is good, focus on the eyes is sharp, so you've got the main points covered.
Just my $00.02 worth - your mileage may vary.
