Another idea for the Hoth battle:
everything for the most part seems to be rather 2- dimensional in that you see stuff coming from the left or the right. Would it be possible to show snow speeders flying towards us and away from us as they are flying around the AT-ATs? Maybe not so much 30 or so all over the place, but say in a scene similar to the one you posted (with Luke zipping up to the AT-AT underbelly) show snow speeders flying underneath the AT-ATs either heading towards us or going underneath and away from us to give some extra depth and scale?
