1 and 2 are too soft for my liking and I would crop in much closer to the subject with only a bit of non head showing. She is very pretty and good expression. Good eyes. Lots of cropping and sharpening would improve for me.
3 has very nice expression. The challenge is that the background is distracting but if you crop you would leave the dark post on the left and cut through her arm. I llike nicks suggestion as a compromise but would be trempted to blur the fence out in his crop and the cut through arm is not ideal. More sharpening would improve.
