This model is amazing but the teeth are kind of messed up. It looks like he has human teeth with a bunch of gaps in them. Also I'm not sure if the "angry" face is supposed to have an open mouth but the mouth doesn't change from the "sad" mouth with the exception of two little dots on the side.
Its not bad, some of the stuff was easy to fix, but theres some stuff missing from the model, like part of the hat and hair sticking out of the hat but other than that its fine.
