Pros:
All the VFX enhancements
All the compositing shots (the Shield Bunker etc)
The idea with Boba Fett flying away from Book of Boba Fett
The blue force fields in the hangars
Endor visible in many space shots.
Cons:
Endor behind the Emperor in his Throne Room
(I think this scene gives too much light and the Throne Room should always be dark. But it’s visually impressive)
One shot of the Death Star orbiting Endor didn’t look complete yet. Maybe it was really hard to pull off because I see that the original Death Star is of bad quality in this scene.
All the scenes with Palpatine is too dark and black. I prefer the blueish tint over this. But as I said, it’s a personal preference. 😃
Some scenes look too polished because some AT-STs for instance look bad. They were bad from the beginning but too much touching up in some scenes give them more presence.
