I actually played with a pose like this as well, but decided against it. I think your hands are too dominant and detract from your world weary expression - otherwise this is a good character and emotion study.
Your composition works well. I immediately fixated on your eyes. I want to say that more of your hands in the shot would help, but I am not sure if doing so would take the attention from your eyes. Nicely done.
Very nice. Out of focus hands are taking a bit away from it overall though, in my opinion, because they're actually brighter than your face, so they're the first thing I looked at. Love the bokeh and the expression (or what there is of it) ;). Other than the hands, it's a great portrait and well done.
