I know the look (! you'll find out later why) nice simple composition, good lighting, your eyes could be little more focused or sharper, and a bit more light in your eyes... not too much, just a bit more would do better. Good photo :)
You should've used the full 640 resolution to maximize the viewable detail. The shadows under your eyebrows create an overhead looming feeling, nice! BB
Two things that would help this shot. First off it's too small and you can't see the details. Second off, a bit of catch light in the eyes would make them appear more alive...
