Ady I was watching Empire a few nights ago and noticed how bad the Wampa looked when it turned and screamed after Luke cut it's arm off. The jaw just drops open very puppet like. I'm not sure if you're even going to be keeping this shot because I know you're going for more of the original scary feel that the GOUT Empire had, but if you do decide to keep it in could you do what you did to some of the Cantina Aliens and give it more life some how?
