Great work, indeed. But do you have something against drawing legs?!
If you really must know, my mother was killed by a leg. I avoid drawing them at all costs to keep myself from spiraling into crippling depression. Thanks for unearthing that repressed memory!
Like Stogie said, it's just a framing thing. I've been making these images so far with use as avatars in mind. I'm not planning on switching my own avatar, but I still like this kind of project. It keeps things a little simpler so I can stay focused. The Ness picture I'm working on is a full-body shot, though, so no worries about legs on that one.
