I'll just add to the multitude of responses here with my initial reactions.
- The scene in Obi-Wan's hut was well edited. I never saw a problem with the original version, but after seeing this I must say the conversation seems to flow more naturally.
- The escape from Mos Eisley is great, Han's maneuvers are much better than before when he just veered lazily to the left.
- Regarding the severed arm, I must say it looked a bit odd at first, mainly because I'm used to seeing the furry hand. I do think it looks good enough, but after seeing NormanS's work, if there's any way to add his version into the DVD releases it would look that much more convincing.
- Right after Tarkin's line "Terminate her, immediately" the engine glow on the Falcon is too high and slowly falls into place as the ship flies. It's always been like that and isn't that noticeable. I don't know if it's in your power to fix, but if not it's no biggie.
- The lightsabers look a tad bit fat in some shots, but overall look great. I like how the colors are consistent from shot to shot now.
- I liked the new Death Star reveal after the Kenobi Hut scene (and the lighting looked good to me)
- The lightsaber fight now looks much more energised now. It's amazing what just a little editing can do. The addition of Battle of the Heroes surprised me. I didn't expect to hear any prequel music (or any music at all in that scene for that matter), but it was subdued enough to not overpower the scene, and the musical cues fit well into what was going on.
- The Death Star battle and the Tie Fighter entrance in particular was absolutely brilliant. I love how there are Ties everywhere in that shot, rather than just 6 of them. 6 villains vs 30 heroes isn't very dramatic. Although upon closer inspection, the DS in that shot does look like it has some funky motion blur or something on it.
- Luke's reaction to Biggs' dust-biting is more realistic now but not overdone.
- I didn't think it would make much difference, but seeing the Death Star actually starting to fire as it blows up really ramps up the "That was close!" factor at the end.
Thanks again for all the time you put into this!
