Well, there's nowhere to go but up from here! I thin k the closest you came to success as on the last shot, but the whites are all blown out. #1 is hurt pretty badly by that bright, OOF< distracting background with those ugly tree limbs in it. #2 has some odd Dutch tilt, for no apparent reason, and appears OOF. #3 is a horizontal for no apparent reason--had you turned the camera, we could at least have seen a bit of her, but as a horizontal it's just a floating head on the left hand side and a bunch of uninteresting, out of focus background on the right hand side of the frame. You did use the light that was there fairly well, but it looks like there's plenty to improve upon in your second shoot. Watch the edges of the frame, and especially cropping off of feet and hands, and think about shooting verticals much of the time on close-range, single-person, female fashion shots where the subject is standing up.
