A fellow, nicknamed Ramshackle Curtis, commented on the lead adventure forums that the knees didn't appear to protrude enough. He went as far as to attach reference to back his critique! What a thoughtful thing to do. I patched the knees up to have more strain against the fabric and mass.
Also, I noted from a certain angle the somewhat out of proportion arms seemed freakish weird long because of how the thorax seemed to be cut off from the arm so I padded it up to look better.
