First, the Veers death sequence:

You used the exact same shot of the AT-AT's head exploding, and it's incredibly obvious. Doesn't work so well - I frankly think the sequence works fine without Veers' death, anyway.

Now, the "lightsaber building" scene ...

Random shots of Luke talking to Yoda played under audio from the radio drama, which doesn't even sound that much like Mark Hamill? Um ... no, doesn't work so well. And I'm pretty sure I've seen that first/last image in someone else's mock-up YouTube video recently, zooming in/out in that exact same way - if that's true, you've given that person no credit, and that's not cool.

Just my two cents.
