In the Battle of Hoth, there are multiple groups of AT-AT walkers. I suggest (re)composing in additional walkers in various shots so that we can get more continuity between shots of walkers. For instance, one group of walkers can become the same group as in another shot, etc.
When Luke crash-lands in the snow, there are two AT-ATs. Luke crashes right before the second one, which is behind and to the right of the first one. I assume that it is this walker that crushes his airspeeder.
Later, the walker that Luke destroys with a grenade can not be any of these two, because the first walker is absent, but there is an additional walker far behind them and to the left.
I think it would be great if the walker that crushes Luke's speeder could be made into the same walker that Luke later blows up. I think it makes sense because it is the walker that is closest by, and it also means that Luke would get back at the walker that crushed his speeder.
This requires 1) that the third walker further behind is composed into shots of the first two, 2) that the first walker is inserted into a shot where we see the exploding AT-AT from behind.
Now... after writing down the wish above, I checked the old script: In the script, the destroyed walker is standing to the right of Veers' walker as he is destroying the Rebels' power generator!
Whoa! I think it would be really great if someone could pull this off.
It would mean that it would have been Veers' that had shot down Zev and Luke's snowspeders!
