The first shot seem awkwardly posed and a subject hardly ever comes out well with the head tilted that way. It also seems to have a pinkish cast. Dress needs smoothing as it appears wrinkled. Cropping out the elbow and hand doesn't work well. The second shot is very nice. Good pose, very playful. I like the shot but cropping off the bottom of the foot lessens the effect. I suspect you cropped it off when you took the photo. Last shot is average, but a bit flat and lacks sufficient contrast, in my view. The head is nicely posed and this would have worked better as the head pose for the first shot.
