there isn't a strong sense of subject in this shot, and the hand reaching down (or up?) confuses me as to why it is there. The background looks nice, the lighting is pretty good.
The lighting is good. I like that the motion blur has purpose and wasn't just added with no relevancy to the subject. What this lacks though is it's a little on the boring side. It doesn't capture my attention and hold it.
Nice idea. Your white point is off though...there is too much magenta in this...and I think you would have done better to lose the white bit of paper (filter?).
