Just watched the new clip... WOW.
Love the pan shot with the side view of the AT-AT (and the AT-ST walking on the left) as well as the new shot from inside the cockpit shooting at the trench line. The continuity with the backgrounds is insanely well done, especially now that if you look outside the side shots of Luke in the snowspeeder cockpit the background has multiple layers of mountains and terrain.

I know how one of the issues (if you could call it that) with the original EMPIRE attack scene was how some scenes were foggy and others showed a clear sky. Even then you had ever changing mountain typography. Now you would never know it wasn't all shot in the same place.

It still just amazes me at what one can do on a home computer.
