nice video Teyon

Hope ya don't mind that I painted stuff on your pics.. 
you might want to get rid of the pole.. vertex connecting 6 edges.  One of the things that jumped at me.. besides the back, is that you're using a lot of edges to create her breast, but you have one edgeloop around the shoulder?... the shoulder is probably going to have a lot more movement than her chest so it'll probably need a little more loops.  One way to help the shoulder along is to kinda follow the direction of the blue lines I drew on there.  The breast should be fine if you get rid of 1 or 2 edgeloops, just tweak the remaining mesh to get the shape you want.
