Vilters, the breasts don't need to be lowered - perhaps the upper edges of the breast could be smoothed out but if they are lowered any further they'd go into her abdomen area and on a woman so slight in frame, that would look odd. Not out of the realm of possibility - breasts can come in all shapes and sizes - but still a bit odd.

I've always felt the trouble with you trying to explain the position of breasts is your use of language. "Lowering the breasts" implies lowering the entire breast area, not just the small part that may (or may not as shown by the attached PHOTO) be an error causing the shading you're seeing. 

 

Now I have no vested interest in this character or model  and I don't deny that SOME women may be shapped the way you describe. HOWEVER, I do want to point out to you Vilters, that your idea of what is "the right way to do breasts" is subjective and based entirely on personal taste and limited experience. Until you've seen all the breasts in the world, you can't dismiss the shape out of hand if it is in the realm of possibility.  (sorry folks, this has been an ongoing battle of sorts lol)

 

That said, there are definite problems with the arm raised position , as the breast completely loses its shape and double folds (which I am fairly certain doesn't happen, even with implants). You are right about the hip crease - that could be softened a bit. Oh well, I'm not going to tear apart the model it's a good job and any new model is a welcome model.
