Interesting to see what you are initially planning doing with your Wampa sequence. I'm curious to see if you end up making the first seen 'yellowish nose and eye area' design with hair covered horns, match up somewhat with the later 'lair' design that rushes at Luke, which features a 'furry' nose and eye area, prominent ears, and protruding horns...or not. I'm not expecting an answer to this at the moment by the way, but I flagged up some options recently, and accept things may even stay much as they stand.
Something I'd REALLY love to see improved would be that dreadful shot where the Millennium Falcon turns on it's side into a 'crevice / canyon' after skimming over the surface of the large asteroid evading the tie-fighters, and there's an explosion. The very poor colouring and effect of the shot at this point look awful compared to the rest of the whole sequence, but I don't know if you are able to improve on things in some ways. Fingers crossed.
