Really good progression!
Your first model is really good for an introductory class! Really great concept.
If you go back and revise some things, take a look at her hip shapes; with full mind that you are learning anatomy (so am I, its life long I think, lol).
This is just personal taste and opinion (general; applies to all female models);
The man’s brain is neurologically tailored to find attractiveness in the hips, as it an indication of maturity, health, and gender. In ancient Greek statues, this was such a prevalent distinction of beauty that they made women’s hips super soft, with large horizontal shapes. One statue/marble sculpture that exemplifies this fairly well is : Venus De Milo ; it is nearly hyper-stylized, as there are definitely women with hips like that in reality, but it can be used as a basis of how attractive feminine hips look.
You can also take a look at how YsaleXand Xada does them (and the female form in general).
They use different methods of execution but both artist produce fantastic results that can be learned from outside of strict anatomy studies (not discounting those too).
