I too noticed that the lasers look very grey, like they'r planes textured like a laser shot, and haveing transparency. For me, the size of the shots was allright, I would suggest to add a shaper glow. Maybe that would help?
About the movement thing. Well, have you ever tried flying in formation in a space sim like freespace2 with some friends?
We got the same effect as here, and sometimes we got bored, and moved around jsut for fun, but even when in strict formation we allways moved around a bit (cause we could never point the nose of the ship at the corret spot, thus never got on a totally paralelle vector).
I think it's a perfect little effect of this movie. I'ts not too much, and not too little to notice.
I also animated some formaiton flights before, and I allways had to add this "unnecesary" motion, otherwise it would have looked totally unrealistic for our eyes
I watched it again, and I have to say again, great work there!
Even the smoke starts to looks fun, just sometimes gets very scarce and loose (when the fighters pull hard manouvers, the density of the smoke gets too little, thus showing individual circular puffs).
