That clip made me to resee the arena battle and GOD how bad composited are the droids! The shadows are under their fit are missing sometimes they are floating over the ground and some elements are in bad place...

The colors from the other side is a bit mixed up and the bluescreen elements/actors not coorporate so well.

Also a good thing is to show that the Jedi are smart, but the droids were hundreds. What i mean is at least to show a Jedi effort to use the force to close/collapse the gates that brings the droids but are too many to hold them.

Plus when the gunship arrive and take them away, after a short dialogue we see lasers from the ground to try to hit the ships.

The lasers are coming from the wrong directions..
