All of the Tatooine sequences have been much improved, with much better contrasts. Mos Eisley looks totally solid. It looks like you did some work on the Yavin launch as well, as it seems to be clearer than in the previous version, as do several of the model shots.
Colors seem stronger and more natural throughout. There is a very nice “filmic” look to this edition, much more so than on any of the official discs.
The chapters are kind of all over the place, but that's already been mentioned.
The very head of the shot with the Falcon blasting out of Docking Bay 94 looks a little strange, like the footage was looped. This wouldn't be so noticeable except that one of the commentaries points out a gaffe in the following shot (somebody leaving the cockpit behind Han), prompting a quick scan back to check it out, which puts that shot under a bit of scrutiny.
I'll keep looking for things to point out to you, but at the moment I'm just bowled over by how much this version “pops.” It looks like a photochemical process, just like it should. Call me old fashioned, but I like it when films look like films.
Very eager for the Blu-ray version with the lossless audio tracks, especially the 1985 mix option! The commentaries are a really nice touch — whenever the Special Edition changes are mentioned, the absence of them on the screen just makes me smile.
