I'll pass along some observations that I think might be of some help in the future, just observations about pictures of women.
It's interesting how soft and gentle the lighting is in the contact sheet's 30 frames, contrasted against the more dramatic lighting you have in shot #1, and to an extent, shot #2. I really like DSC_8507 and the way the hair was very gently accented on the right side of the frame, and the way the shoulder has a nice accent light too. (Shot #1 by contrast has much hotter accent lighting, very specular on the face and ear, I would add a mylar diffuser to cut the hotness of those two lights used in Shot #1).
I'm not sure what work was not liked, but the contact sheet has 30 images to evaluate, and there's one thing you did over and over: her face is pointed in the direction of the main light, and her chest and torso is in the same orientation...that's a bit more of a masculine head/shoulder alignment than a feminine one. Every one of the 30 images on the contact sheet has the face and torso and shoulders in the same alignment, and there's not one frame where the body was turned away from the light and the head brought back to it, and if you want a 'trade secret', well, that's the one you need for portraits of women: slim the torso more, by turning the body AWAY from the main light, and rotating the face back toward the main light, which is slimming, and it's visually more "dynamic" to have the face and the chest area in differing alignments, pointed in different directions.
8510 and 8511 have full-face angle, and shoulders in alignment, which can work (I do not mind shoulders square if I want to create a powerful-woman vibe), but the sides of the frame are "crushing her"...she just fills the frame entirely and looks awful; note that pulling the frame wider, as in 8513, makes her look about 30 pounds lighter? But her chin is dropped too much in 8511,8512,and 8513.
Just in-general on the contact sheet: she needs more projection of the chin in many of the frames. In some, her chin is down, and her pretty face looks less-than-ideal; her torso, neck, and chin position is not "taut" enough in quite a few, she looks slumped, not in an erect and projecting body posture. She is clearly not a model, but she is attractive and the lighting is soft and pleasant enough, but the aligned head/shoulder axis in every single frame, and her less-than-taut body position and lack of neck and chin projection makes these look not that great. The posing is just not quite "dynamic" enough on the contact sheet.
