Gotta say, I agree about the pelvic area, it does look pretty unmatched. I remember fiddling around with it a bit to get it right, but ultimately didn't quite end up with the a good result. 

Thanks very much for the comment. :)

Transparency counts as a colour, so this piece has a 4-colour palette, not 3.

This is very readable despite the size and limited palette. The area where the legs join the torso looks a bit odd to me though. I feel like the thighs should be wider, and the shadows there seem too deep.
