During the part where Han says "I'm going in closer to one of the big ones", we see an outside shot of what is presumably the 'big one' in question. However it seems to be approaching the Falcon at a speed indicative of something much smaller. I would suggest having it completely static, while the rest of the scenery moves around as normal, to convey size.

That is something that has always bothered me as well, and that is an excellent suggestion for fixing the issue. Even if it stays more stationary in that one shot, and the Falcon is shown reaching it in the next there is always the logical assumption of tiny jumps in time....something films do all over the place, and something that the SW films are definitely full of.
