This is a very nice portrait. I think that the angle and framing/cropping are good, and the focus is good as well. The only thing that bothers me a bit are the horizontal lines going through the dark areas on the left of the photo. You did an excellent job photographing glasses without glares or reflections. Very nice. ~Heather~
The expression on your face really makes this photo captivating! Looks almost like a smirk, like the viewer is in on some joke with you and everyone else is "on the outside" of it. The glasses/string on wrist tell something about your personality, give this an artsy feel. If the contrast were bumped up slightly, I'd like it even better. But it's great as-is!
