Upside Down Underweared Pose in 1 Hour, 50 Minutes

Done as part of a 6 hour class.

My current goal is: I don't know! I am an absolute beginner; I'm here to study the basics of rendering

This is what I really don't think it's perfect, but I really, really think that this is getting somewhere in rendering the pose precisely, all informing my memory and all not looking at the pose normally. So, how do you love my picture?
