>>21613274>this was the last chance for Erionthat's stupid, not even to change the underlying anatomy to get square jaw to not be so retarded?
but anyway, I think pic related is how it's supposed to work:
Right is old round jaw (or one interpretation that allows it to protrude from the face)
Left is new square jaw. It's pretty much the same except the square jaw doesn't have nearly the same range of movement as the round one.
