Life drawing

The model was quite different for me to draw and actually difficult, because it wasn't very clear how the skeleton is standing. I took it as a challenge and drew what I saw without setting base of the pose. Just drawing the shape not sure where it will lead me. Of course my anatomy is a bit off on the four fast poses, but then I was also trying to define the shape with only one line. Then we had to draw without lines... so hard :X *smudge smudge smudge* no lines anymore! Drawing cloth and shading it correctly is still an issue though.
