RE the new Yoda tweaks - here's my observations (which I wrote as I watched it the first time):

1 - It looks a LITTLE too Photoshop-smear-ish - you need to try to tweak the mouth without moving the teeth as well. One or two tweaks morph his teeth a little as well and make it look too fake.

2 - When yoda says "Looked away," it's PERFECT.

3 - When he says "F" or "V" syllables, see if you can make his lower lip behave the way it really would (go inward a bit) - that part still looks a little puppet-y

4 - "What he was doing!" also nearly perfect.

Overall, it's pretty good. I've always thought that Yoda in this scene looked a little stoned - maybe something could be done about the eyes?

I think if you do one or two more passes on this it'll be perfect. It's close, and there are several instances where it IS 100% perfect, but it's not quite there yet.
