It depends if the picture is to show your artistic bent or your photography skills
IMO
1 skin tone blends into the background too much
2. Looks to be a picture more of the dial on the camera than the woman
3. This would be my No. 2 pick - just missed No. 1 by not having the focus on the eyes
4. Best of the set, if you had the lighting/focus on her face as you have on her arms would be a real winner
5 Focus on arm instead of eyes and much too blue
