I find it an interesting image, although it could be more interesting. Putting her eye near the center with her fist below, makes for a somewhat blunt and static feeling. Also, a little more light on her face would better delineate her expression and eyes. A little touch-up with the blur tool could know down some of the grainy noise as well.
Thanks for all the comments. I try to frame or crop the image to make a better use of the space, specifically to make the image more dynamic.
Regarding the noise issue. I should have rotate myself around and expose a bit more to let more light to the subject. Of course the noise reduction trick will have to be done better.
