I played through it a few times as both the Republic and CIS, and I have to say that it was incredibly fun. Pretty much everything is set up perfectly - unit count, planning, foliage density, etc. The only real bug I found was that the blasters on the AAT were missing their firing sound. Other than that, all you need to do is move a few objects a matter of inches to get rid of some gaps.
Screens of gaps between objects:
Another small visual adjustment I would make is with the halos around the sun. The bloom effect doesn't entirely cover them, so the sun looks kind of strange.
Some glamour shots:
I wish I just had a video recording of the whole time I was playing; there were some really cool moments that just couldn't be captured by screenshots. For example, as I was taking cover behind an AAT as a battledroid, a clone trooper was blasted into the air by an explosion, landed on the bottom platform of the tank, and rolled off. Normally events like that don't look so great in Battlefront because of the lack of any ragdoll effects or anything of that nature, but somehow the animations worked out in this sequence to look incredibly realistic. Situations like this were made even more intense by the fact that I was playing in first-person mode for most of the time.
Anyway, good work. This is already a very polished map, so there's really not much you need to do with it.
