Drawing the Female Torso

I've been doing a lot of male/female torso studies lately and this is the product of this. I expect to do a male version eventually, distinguishing the different body types( there is more than one, I'm told) and it'll have a "no-no's" section just like with the female torso one above. Also... and please don't hound me on this, but I realized I didn't draw faces on any of the models. This isn't a face tutorial, and I didn't mean for it to be interpreted as anything objectifying. A lot of mannequins don't have faces, and while I find them creepy, they don't offend me.

Hope it helps. Now go draw!
