This is just a suggestion to Adywan that I have for a Return of the Jedi re-edit. First, the Death Star II begins to fire at Endor just before exploding. Second, make the explosion more like a supernova with the rate of explosion scaled to the same scale as the 500-mile (900-km) Death Star II, and continue the same explosion as seen on Endor.
I've noticed at least one mistake that still remains in Star Wars Episode IV, and possibly another one. In the Mos Eisley scene near the Cantina, I've noticed problems with shading direction, where for no reason the shade seems to change direction. And in the Death Star in the control room, right after Leia leads Luke, Han and Chewie into a trash compactor, a storm trooper still bangs his helmet on the door on his way in. I'm sure there's no way around it other than to completely redo that scene or possibly crop it to cut the open door out, but to the untrained eye, viewers barely even notice if even at all. Just thought I'd let you know.
You mentioned that you took out the Jabba the Hutt scene. That scene connects Episode IV with Episode VI as it was meant to be. In fact, I seem to remember that the book mentions Jabba the Hutt's conversation with Han Solo. I would like to see that scene put back with improvements, not removed, unless there's a good reason for the removal of it. I love the rest of the movie, though.
