I really like the editions you've made but there's a couple of things I'd like you to consider. The changes you made to ROTJ I like but I can't stand the Special Edition Sarlacc; I'm sure many here would agree.
Most importantly, I think your color correction might be off on all three. You_Too, Adywan, and Harmy (members of this forum) are exceptional at color correction of the movies and maybe they could help you out. Granted I would rather have basic correction on them than have it like the Green shifted Star Wars DE 2.5.
Edit: I'll watch them again and see if I can find anything else you can improve upon.
