#1 and #3 have some compositional problems. I don't think the empty space helps the images much and #2 ends up in almost center frame with a pose that really doesn't like a center frame composition. #4 is very noisy. Scarily so and the eyes have gone from a perhaps strong emotion to 'chick is scary, run for the hills.'
#2 on the other hand... that's a very nice shot. Good dramatic lighting, good pose, excellent use of filling the frame. My only wish is that the hand were nailed in the focus as well, that the DOF were a bit deeper. Her hand blurs a bit and I think the ring is almost as an important element as her face. Excellent work on that one, though.
