Another sketch. This time, a body with no head (admittedly, I ran out of room. need to pay more attention).

Pretty happy with the curves, the left breast is still a little weird, though. Gotta work on that.

If I'd had room for the head, this would be Purity, tied/chained up to a post. No doubt a clever ruse on her part to get close and learn the villain's dastardly plans!
