My shot-by-shot impressions:
1) The closer proximety of the SD makes sense, along with the "blockade" and the blue hue to the engines.
2) This is my most anticipated scene from ESB:R! New asteroid elements, along with firing TIEs = tasty!
3) Color correction not withstanding, the recomposited AT-ATs in the rear look great. And I certainly don't mind the red windshield removal.
4) A good update to one of the SE's biggest FX blunders.
5) Bespin not in a gloomy haze? New background elements and sunlight! Awesomeness indeed.
6) ditto.
7) New macros give a more modern look. Not nesessary, but a nice touch.
8) Aside from the officers being further apart, I love this shot! Pretty much new elements all around and it works! And Hoth's perspective in the first window has been fixed.
9) Nice grey bridge with visible stars
10) good matte enhancement and the sabers aren't blooming!
11) nuff said about his one. it's perfect!
12) more lightsaber tweaking goodness
13) window restoration! Now consistency's afoot!
14) again grey interiors, with more continuity changes. Excellent!
15) good clean trench background. nice and bright!
16) I can't wait to see this one in motion!
Bring on the trailer!
