All three have problems. #1 has too bright a hot spot behind the model and the background doesn't really work for the photo. The pose looks very strained and if you're going to do a full figure shot, why crop on part of the foot.
#2 is also has the too tight cropping problem with part of foot just barely cropped off. That's a small detail, but it jumps out on a subconscious level to most viewers. Also glamour works better with eye contact and that would help this one out. And again too much hot spot on the background. Does not help the photo.
#3 has the most problems with blown areas on the face and the same background problems. Positioning of the arm on the left looks too "posed". No catch lights in eyes.
In fact no catch lights in any of the photos.
Overall, need to pay more attention to the lighting setup and ratios and then work on good poses and if you intend to do full figure shots, then be sure to get the full figure in the frame when you shoot the shot.
