1.2 Original score for that scene was composed but not used for a good reason: this duel is much scarier without the music just as well Wampa is scarier if one doesn't see it.
1.3 Third reason for not adding this would be that it could be used only in two cuts in the Carbon Chamber and not on later already scored duel - parts. That means, it would appear pomposly at the main Carbon Chamber, destroy a claustrophobic feel and not get anywhere (to culminate) after that (in all other movies it does, even in adywan's NewHopeRevisited).
1.4 Fourth reason for not doing this is to avoid "bastard - scoring" which never happened on SW until postproduction of AOTC, which has a lot of TPM - music in the battle (you can read about that in a score - thread of a member "good musician").
2. Pissed "BRING MY SHUTTLE" line should be back but also trying to save walking on the bridge-wideshot afterwards, with shuttle erased from the scene. Maybe it could work well, if not, please leave it like the original (1980).
2.1 VADER'S ARRIVAL TO STARDESTROYER was ok in the SE but the use of music at that scene made the movie STOP and stormtroopers in the background looked fake. If a lot of people incl. adywan still want this scene to remain in the movie after all, this two issues should be solved very properly because on that point of drama there is no place for any conceptual or technical mistakes of any kind. I could try to make a few musicmix - models for that scene to use something which keeps the feeling on the move
3. Before the Hoth - battle, "Imperial Fleet coming out of lightspeed" is mentioned. We don't have to see it coming out of light speed because Vader gets pissed because of it anyway, but it would be great TO SEE THE FLEET in the Hoth system, to feel that power on some point before or during the battle. It also doesn't need a big introduction because it was already introduced before.
3.1 There could be more shots of rebel ships escaping the system (there is a whole rebel base evacuating!!!!!) and some out-of-order-stardestroyers due to ion cannon-shots, for example , when Luke flies out to space.
4. There were more of that IMPERIAL 2-LEG-WALKERS (later to be seen a bit modified much more in Endor - Battle in ROTJ) planned during the ESB filming, but due to time and money problems never finished (look for that in "Building Empire"- documentary). There is only one shot in Empire using this walkers and there should be more of them around accompaing At-At's in almost every floor-shot At-At - scene. Also, shooting snowspeeders could destroy some of them when shooting. This would be an improvement in the style of your improvements on ep4 - Yavin battle.
5. Making that annoying TAUNTAUN STOP-MOTION corrections may be complicated, but worthy doing.
6. BESPIN should not look as giant as Coruscant, but like a small mining colony. It helpes the claustrophobic no-way-out feeling of our suffering protagonists. Some of the most beloved movies happen in some closed space, like Nakatomi building in "Die Hard", or Nostromo in "Alien", or Alcatraz - Island in "The Rock". Bespin is also that kind of place and should not be made to New York with every new edition. That SE wideshot - scene after Lando's warning-speech looks already too big and out of place with too many people walking outside reacting weirdly synchronised. Can you erase some buildings and people from that scene to fit better and look more natural? Also, on some later point seeing ships evacuating would be great but again, in a tasteful logical size (I noticed anyway, adywan has a very good sense for the right measure).
6.1 If any new backgrounds made for anything, it should be tasteful and size -fitting.
6.2 That SE computer-flying-shot of Bespin-by-day should be softened in movement to fit the rest of the movie, not suddenly looking like a computergame-intro with unorganic camera turns etc.
7. Before entering Vader- Restaurant in Bespin we see windows in the background. After catching Solo's gun, stormtroopers arrive and there are no windows any more but decoration. Please repair that SE mistake by PUTTING ONLY DECORATION, because again, it helpes the claustrophobic feel more then windows and beautiful sunny day outside.
8. RE-COLORING OF CLOUDS, especially dark parts. This SE - syntethic blue-grey looks weird.
9. Kerschner's decisions about human reactions in actors interactions as well as audience response on this and that were all right in the place - that's what made Empire such a good movie, because Heroes and Villains really care. One of ideas which came from that wise and very natural approach was NOT SEEING ACTUAL WAMPA. I would stick to that decision. I don't want to see that documentary - shot of him eating and prepairing for winter. I want to escape from there ASAP, and that's what I want Luke to do!
If I remember or notice something else, I'll post it later. Thank you adywan for collecting ideas. I hope, you'll have fun with it and make that most beautiful photographed movie ultimate edition for most of fans.
