It looks like a lot of people have already given great feedback but I just wanted to say that I love how ambitious this edit is. Your ideas are pretty much uniformly great, and go a long way toward making these characters feel less wooden. I do still think the execution still needs work in a few of the clips you posted though. I’ll try to post more detailed thoughts at a later time but here are a few things that jumped out to me:
-The presence of Clone Troopers in the first Kashyyyk scene would imply that they are already receiving Jedi/Republic help, no? Unless the idea is that Yoda and his troops will supply additional reinforcements.
-I feel like some of the clips where you try squeeze in a bunch of extra lines during what was originally silence feel a little frantic. Similarly, when you try to construct entire sentences or conversations wholecloth it can sound a bit like a Star Wars character soundboard. I would try to be a bit more selective about employing these techniques.
-One thing that didn’t work for me in any of the clips was the color grade. I’m not exactly sure what you’re trying to accomplish with it, but the warm “instagram filter” look doesn’t really resemble any other Star Wars media, so I wouldn’t say it’s helping your goal of making the movie mesh well with The Clone Wars or the OT. Frankly, ROTS is probably the best looking prequel movie already, with natural colors and a clean digital look that complements the animation in Clone Wars well.
