I think the animation Adywan has done for the cantina scene is great as it is! Rememeber they are ALIENS so may not move exactly like humans! Some movement/manipulation is better than no movement/rubber masks.

I would make the first alien with the yellow eyes who pops up at the start blink , I reckon that would setup the shot for showing that all the Aliens have facial movement.

The Greedo scene is still fantastic. Wouldnt change that one bit now.

It will be hard if not impossible to watch the original SE2004 discs after this!!
