Thanks a ton, Harmy!
The covers look pretty snazzy too, and should look great on that silver paper! However, if I may critique (okay, this looks like a huge rant, but really it's just a bunch of minor nits—it just runs really long because I'm bad at explaining myself):
The cropping on most of the images looks awkward. I'd try to get the whole image in there rather than crop off Luke's ear or Chewie's forehead. Watch out especially for places where the edge of the image intersects an edge or corner of something in the picture (like the side of Luke's face, the top of Han's hairline, and the bottom of Tarkin's chin on the ANH box, or the line of Luke's lower arm on the ESB box, or the bottom of Leia's bikini top on the ROTJ one). This is called a tangent and is generally something to be avoided because it flattens the image. The idea is either to get something totally in the clear, or crop it cleanly and decisively. Also, I'd make the title text on the front covers bigger, and maybe move the images up to put more white space (well, black space in this case) around the titles to give them more importance.
For the backs of the covers, I'd check your margins on the text. "The battle continues" should line up on the left with the block of text beneath it, but it's edging a bit left of where it should be. "The Empire falls" I'm not sure about, I'd have to pull it into Photoshop to check, but I think it might be off too. I'd widen the running text; it looks squished and hard-to-read as is. Also there should be no apostrophe in "its," there's an extra space in "THE EMPIRE STRIKES BACK PARTLY DESPECIALIZED EDITION," and the "the" preceding "RETURN OF THE JEDI" should be in caps too since it's part of the title.
I think you could get rid of some of that mess of logos and notices in the lower right. For instance, I don't think the copy protection logo, the Video Packaging Review Committee logo, and the notice that goes "The copyright proprietor has licensed the picture contained in this video cassette . . . " are really appropriate to this release. Getting rid of some of those might allow you to move down the images and give your running text some room to breathe. (New idea—you might even shrink the largest image, since it's nowhere near print resolution anyway, and then have a small bullet-point list of things you've restored. Han shoots first! Lapti Nek! Original Cloud City buildings! etc.)
Also, I know that you want to showcase the restoration you did on the Sarlaac sequence, but I don't know if that's your most dynamic image to use as the central picture. I might switch it with either of the other images, or maybe use a cap from a different shot or sequence altogether, one where you can see someone's face or at least a more dramatic silhouette.
Anyway, if you bounce me the PSD files, I could give 'em a whirl. . . . Heck, I could even take a crack at them as they are now, just to show you what I mean.
Like I said, though, they do look snappy. You did a nice job with them, I hope I haven't stepped on your toes here. I'm just concerned that your covers are as good as possible so they do your own work justice! :)
