Lovely shot - the perspective works well. The real strength here is the calm of the women with the lines leading to the hand and face. What muckpond said - the motion blur really draws the eye in, and then doesn't give the viewer anythign to be interested in. I think you have struggled with the colour depth with the bright guitar and dark face - difficult to make a balanced exposure on that range.
It's nice but it is not clear who or what is your main subject. The guitar is nicely lit but her is too dark, the harsh light in her hand is a bit distracting.
People (including me) look to the brightest part of a photo.. it is natural. Here you see that that leads to the hand and not her face. I really do like your idea of letting the guitar leading you up to the face, but light should support this and not work against it in my opinion. vote=5
