Well, in the very VERY first shot of the Imperial fleet (the port-side of the bridge passing overhead) the BG destroyer that was medium-shadow density is utterly black in the '04s, and all of the shadows on the TIEs chasing the Falcon prior to entering the asteroid field likewise are the same black as the BG starfield, making chunks of wings bleed seamlessly into the BG. I probably notice it because of how much I have loved both of those sequences since 1980. It's obsessive, but then again, we're talking about minute re-construction of details to a thirty year old film at this point :) All of the space stuff suffers from this re-timing of the film. Anyways, it occurred to me by the end of my last post that you likely would have to be deep into prep-work on v2 before you'd know what you wanted to address anyways, and therefore there wasn't much of a head start we could get for you.
