Just a nitpick (but that's what it's all about right?) but the two laser bolts that hit at 3:07 and 3:10, just before the 3 ships enter the canyon, the dirt should blow up and OUT, not up then BACK DOWN. The gravity would be too small to have such an effect. Luckily this should be an extremely easy fix.

Other than that, beautiful work. I really wish you'd put out some sort of tutorial on your rotoscope techniques for the rest of us fellow editors. If I had a better understanding on how to do that I'd be doing way more Star Wars edit work on my own.
