The pose seems to be (though hard to tell in a 2D image) one where she is pushing her torso forward, almost peacock strut style. I have seen many a pose whereby a buxom lass has pushed forward her top half alluringly but not to then put her hands up and pull back the very things she is trying to push forward.

Ok, ideas:
~ She is a very pretty girl and a lot coule be made of her face without worrying too much about her body.
~ To include her body, use poses whereby her arms are allowed to drop so that her bony prominences on the shoulder will not be a problem.
~ Likewise, any hand shots should be flat-handed. The best position is a natural curve: relaxed hands are never flat, you have to use muscles (anterior digitalis flexoris if I remember my anatomy correctly) to hold the fingers straight, relaxed they fall forward to a natural slight curve. If these are 45 degrees on to the camera, the joints will not stand out as they do when in 90 degree profile.
~ With any pretty giirl who has a lovely face and body but slightly more obvious joints than we would like, the key is to have relaxed poses whenever possible. The shoulder prominences are being pushed up because she is pulling her elbows in to her body. If her upper arms were more relaxed, even within the same pose, the difference would be marked. Test this yourself: put your hands onto your chest with arms relaxed and then push your elbows in to your body. Feel what is happening up at the shoulders and you'll see what I mean.
~ Watch the effect of lights as you move them around the girl as you will see remarkable differences even with just a few inches of movement. I am particularly referring to shadow areas which we need to consider more for any prominences. As a good example, look at Julia's left shoulder (right of pic) and look at the area between the shoulder prominence and her neck. There is more flesh area there but it is in shadow from the prominence. If this area got a bit more light, the prominence would be less obvious. Raising the light source higher would help that but watch for other areas being affected. It might be that a reflector out of shot could put a bit of light in to that area.

This is a pretty lass and I am certain there are some beautiful shots to be had of her in relaxed poses. Keep trying and see what else you come up with. Your commitment to learning the difficult art of model posing and lighting is extremely admirable and I am certain your willingness to pick up tips and ideas will stand you in very good stead.

Keep it up and let's see some more :o)
