An artistic question, if I may. What made you decide to joint the legs of the being at the bottom in such a way? I know it's not an anatomical overlook, as your knowledge of anatomy is quite thorough. (As evidenced in your book on drawing/painting the undead.) So in your opinion, what artistic merit was there in shaping that particular character's body as such?
That's not to say it was a bad idea, of course. It definitely works. I'm just looking for some insight as to WHY it works.
I'm really into this motif of a double wrist or double ankle. It'll show up in my art more in the future. If you look at the Homonculus designs from the movie you can see they also have these double wrists/double ankles.
