since a few people were mentioning a few things that needed fixing, your new shot of Luke & Liea swinging across the canyon, where you said you used a new matt, to make it look bigger, it works but if you look at where the actual ledge, where they were standing is, is much lower than where they look. They look like they swung from the top of the doorway.
still a great movie, & the Death Star Battle is sublime!
