I really like the flipping of the Tarkin shot, I think it looks more aesthetically pleasing.

Btw, I’m glad you’re adding the Imperial March to Vader’s entrance, I’m planning on doing the same for my edit (in fact I’ve considered overhauling a lot of the Empire scenes with Imperial March tunes). I feel like the grand first entrance of Vader should have his theme. I find the original Empire theme in ANH to just be generic and bland. There’s a reason the Imperial March is so much more iconic: it’s much more impactful, unique, thunderous, powerful and fitting. If having the Imperial March in ANH was a special edition change George Lucas actually made then it would’ve been one of my favorite changes.
