I actually even think the angle of the head looks OK. There were times when the puppet's head was lifted or turned and things looked a tiny bit unnatural... sometimes having a replica that looks a little "off" can even make it look more "screenused" looking in a sense.
Just finally read this thread and the amazing work you have done. It's so life like. My cousin has a yoda prop that I always wanted that he won years back from Blockbuster but now this sculpt makes me think of his prop as a kids meal toy.
