I flipped through this video to check out what was new effects-wise. Admittedly, a few things are rough - and that's to be expected when you're pulling from fan films etc. Plus, you're really early in the editing stages. If there were any way to improve the CG matte shots on Coruscant I think it would be a lot less anachronistic in relation to the rest of the film; I would love to see it work properly, but right now it stands out too much to me.
I really liked what you did with the Jabba introduction. It's too the point and by flipping the sequencing of the 3PO and Leia scenes you've managed to make him intimidating right off the bat - and no musical number is definitely a plus. I wasn't a big fan of the pan-down to Tatooine when Vader tried to reach out to Luke with the force, though - again, anachronistic. And I don't mean necessarily in terms of the effect itself, I mean the editing. It feels, for lack of a better term, too modern. It would have stood out like crazy in 1983.
Also a big fan of how you cut down the 3PO/R2 intro to Jabba's Palace via the deleted scene. THAT cut felt really natural to me.
tl;dr a little rough as expected at this stage but looking forward to what comes of this.
Re: Coruscant. That sequence is the best quality video I've been able to find of a shuttle flying through the city. I've spent hours looking. I think the quality is decent, but unfortunately YouTube butchers videos with its aggressive compression.
The use of the Star Tours footage to link Vader and Luke might end up being cut. But I do like the idea of linking the two characters. There are other moments in the edit where I try to show Vader getting into Luke's head, so that moment (poor CGI and all) is telling the audience that although they're worlds away Vader is always with Luke.
