I agree about the violin position, and am not too crazy about the pose in general. The wrinkles in the blouse and pants are also distracting. Tugging the blouse down a bit might have helped. The shot looks too posed to me, also. Maybe if she were holding the violin neck in one hand and the bow in the other, looking like she had just finished playing (or was about to play) could make it more exciting.
It's not a bad shot, but not a good one, either; at least for me.
