Beginning on 2:50, if you follow Lando and the group through the city hallways, you will notice that some of the windows show blue sky outside (even though it was dusk at their arrival at the landing pad). Later on, when C3P0 is shot and the door closes, when Chewbacca shows up, you can see the orange tint from the outside lighting.
You will want to keep an eye on the windows to make sure the outside lighting is consistent.
And just to ask, on 3:37 I believe you mentioned you will be using the original "Who are you?" audio clip. Granted, I understand the voice was the way it was so as to develop the mystery, but would you consider making the voice sound like the Stormtroopers in ANH (with the mike sound and voice pitch)? No biggie, just an idea.
But please get rid of the stupid red thing that was added to the left side of the shot in the SE on 1:11 here (this clip has the original unaltered scene): http://www.youtube.com/watch?v=PHwBJuwpD6E&feature=related. This original shot is so much better.
You may want to consider altering this shot too (http://www.youtube.com/watch?v=xKo1yLgKbK8&feature=related at 3:49). Considering the earlier scenes with Luke jumping down from the carbonite platform, going into the tunnel, fighting in the hallway, and then they are outside a large pod inside the central core under the cloud city - how did they get into the top of the pod?
