Hmmm....I will admit I haven't looked over any reference yet, and I'll apologize up front for not doing so before this post, but the mouth doesn't seem right. Unfortunately, I am blind without seeing some reference with the sculpt photos. Phil, any chance you could show us (me) the reason for the changes to the mouth? I'm not bashing your skills, as it's apparent you have the IT factor with regards to these projects, just hoping you could 'show and tell' a little bit with regards to the current round of changes.
Thanks!
