I've been getting some great feedback over on Flickr, and I agreed with the observation that his legs appeared a bit too thin. I also wasn't entirely happy with the flappy feet and felt they needed to be shorter and more round as exhibited in most of the recent sketches. I also paid considerable attention as to how the limbs would attach to the body, inserting a slightly recessed area on the body so the limbs would inset nicely into their slots while allowing full 360 degree rotation.
I think I also came up with a new logo for the toy line. ;)
