That reminds me... in the SE "extended Yavin Battle" CGI... all the X-wings have the markings for Red 2 (two hatch marks on the wings). Adywan fixed it so that it reflects the proper pilot, except in one major shot I noticed... where Luke is flying away from the TIE and is saying "I can't shake him" the next big shot we see two hatch marks when we should see five.
A minor change.
Anyway, somebody said we see Dave Prowse's eyes through the Vader mask eyes a lot in ANH. Got any shots of that? I can't imagine that's a problem. Everybody knew he had eyes, and the fact that he has human eyes is not really a big deal. The red eyes stand out more from the mask, and I don't think it's a big problem that the suit is completely different in each movie. It's stranger that Vader would wear the same identical mask and stuff for 25 years.
