The pose that you are trying here, has to be one of the most difficult poses i've ever seen and tried to draw myself. You did it pretty good! The breasts are very alluring, BUT her behind or ass looks a little weird. The hands are well drawn, the expression on her face is cute, and the curves on her back once again give a lot of sweet little details. A little tip though, is that the piece of arm that leads from her right hand up to her elbow could be a bit rounder. You know what i mean?
The way you've drawn her legs, and the way they point is very original. it is not something i see often or maybe not at all. So you get a 5 for orginiality from me.
Oi 'mon, great sketch.
