A few other notes:
(1) When talking about the scene where Dac gets into Luke's snowspeeder and they start to lift off, there is a blocky part underneath the snowspeeder used to hide the forklift lifting it up. Is there any way to delete this and "flatten" the bottom of the snowspeeder?
You can see it better in this clip at 1:15.
(2) And will you be working on the AT-AT matte in this shot?:
