In #1 you need to either shoot the profile or turn her face more toward you (3/4 view). There is a rule in portrait photography that says you're not supposed to let the nose break the plane of the face.
#3 I don't particularly care for, the rest look nice though.
in number 1 her pose is ... i guess "fake" for lack of a better word, shes smelling a flower but looking somewhere completely different. just seems unnatural to me. otherwise good stuff
As you asked, 5 and 13 are quite flattering. I wouldn't show her 3 (brutal colouring) or 10 (even if you remove the bruise, her smile is not great). 7 might be okay if you warmed it up. I wonder why you turned a warm person cold?
