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. :)

Well, Ady has said that ANH:R is DONE, he's not going back to it again, especially not for minor tweaks.

Second - adding that scene would kill continuity with Robot Chicken. :-)p
