A very interesting and original piece you have created. I'm very intrigued by this piece since it's not everyday you see a naked woman with a box on her head. It really raises some questions and curiosity that really makes this piece interesting.
As other reviewers have mention, there are some areas on this person that could use some work most notably the curve on the left side really flat and need to stick out some more since women tend to have thick hips and also the curve of her back. Also, I'm not sure if it's intentional but the eye holes of the box would be too far apart for a proportional person; I guess that's the allure of what's underneath. :)
Overall this is a very interesting piece and I enjoyed it very much. Keep up the good work!
