Female anatomy

Critiques of this would be appreciated.
I decided quite a few months back to see how well I can draw a naked woman based only on my memory, and whimsically decided to give it unusual proportions. I've touched up this picture occasionally over the months. I decided to finally show it to people for critiques, because any further touch-ups would ruin the experiment, as I currently have the fortune of seeing the subject matter in the flesh. For I am in an art class. Where else can one possibly see a naked lady in person?
