Experimenting with leg and foot structure for a character. Unfortunately didn't come up with anything satisfactory. I kind of like the top left, but that looks more like a delicate hand to me, than a load-bearing foot. I'm also not sure it would even look very good on the end of a leg. The top left is the closest to the top right + leg, and it looks off to me...

Bleh. Inexperience and seemingly conflicting design requirements suck.
