Well that's just it.....I think it more or less IS already perfect. There's a reason I've come to like Ady's approach to these films.....it doesn't add more just for the sake of it, there's reasons for things to be added....and when possible he adds them into existing shots instead of creating new ones. For example....the rebel troops are all firing away...but at what? Their guns aren't slowing down the walkers one bit and they KNOW this. Imperial ground troops being in the shots would give the Rebels a reason to be in those trenches, firing away. BUT, I'd want it added into the existing shots.....small troopers amongst the feet of the walkers.....the fact that they'd be there doesn't need to become the center piece of the scene in question......just a little extra info to fix an error in logic/continuity. The order of the shots and sequences in the film works just fine the way it is.
