This movie is now near perfect thanks to you adywan! Just 2 things: The shot where R2 parts with 3po in the desert and rolls away over a sanddune still looks extremely fake. It looks like r2 had been pasted into the shot.

The other thing is when Obiwan ignites his sabre when meeting Vader. I think it still looks a little weird and the sabre looks too "fat". Otherwise its perfect! I know this would be impossible to do but it would be cool to add a scene right before the yavin celebration where we see vader in his Tie advanced landing on a platform on Coruscant. Stormtroopers comes to greet him and he forcepushes them in anger over a ledge and then enters the emperors huge throne room and we see a longshot of him walking towards the emperor(playing the Imperial march) with lots of red guards standing in line as he walk , then the scene segues into the yavin celebration. :)
