I think it is the point at which it is Lasers going off and smoke.....

I tried to use prision cell from ANH in my rough cut to fix this point to show the troopers firing and chewie firing back and then cut away..... I am only saying that it might work better to just have the trick still be the thing that actually gets them in and the ground battle is wrapped up before the shield bunker blows up as we still have the battle going on after this point at present which is perhaps more realistic.... But does it really work?
