Don, I like #4, the model seems at her most relaxed though you need to watch for those background distractions.
Don't have the model to look straight in the camera all the time; #1 would have worked better if she had been looking down at the shoe as she adjusted it. But look how that vase of flowers grabs the eye, turning attention away from the girl.
Three quarter profiles tend to be more flattering to the model, use her right side if you do that, it seems to be her better side.

All IMHO, of course.
