Sexual dimorphism Study - w/Artbuddy RavenWilder

When I did the tracing follow-up to my gesture study [here], I realised I was a bit weak on being able to depict sexual dimorphism well. So I did this anatomy study, with the aim of covering the anatomy of the shoulder and the torso - and to work out in detail what the sexual differences are in the torso. I did a couple of quick sketches in the bottom right, to see how this affected my ability to depict male and female bodies. Btw, a pic of the muscle layer itself is here.

This is part of a series of studies with artbuddy Ravenwilder.

As always, any feedback/critique is welcome!

to :iconimprovement-club:: The lower half of the female torse, especially the hips and how they flow into the feet, seem to be 'off' somehow, but I can't quite place what it wrong with it. Could you please redline it/correct it?
