Cool. Very deft modeling modeling too. My only concern would be getting a triped to walk without either defying gravity or having it stagger. I've seen three legged dogs before so I know its possible, but it doesn't seem practical.

I agree on the colors. They work well, but I would tone down the green myself to more of a military olive drab. But that's just me.

Look forward to seeing this done, which at the pace you're on should be yesterday.
