I thought the new hangar matte behind the three talking guys stands out as a little too crisp compared to the actors in the foreground. But it is certainly better than the original.

Other than that, I think the changes (at least as far as I’ve seen) are fantastic. Favorite is definitely the enhanced screens in Echo Base. Hardest to notice unless you know to look for it is the Dagobah matte when Yoda lifts the X-Wing. It 100% looks like it was always there.

JEDIT:
What’s the reason for the pink bacta?
