Something I noticed while watching the recent vid...

It seems the side guns on the AT-ATs don't shoot evenly. Specifically check 0:30 and 0:43 - you will notice the side guns moving, but not shooting. Should anything be coming out of them (I'm not saying they should be constantly shooting, just when it appears they are being used and aiming at something)?

Also, should Wedge's snow speeder cast a shadow at 1:28 when he's circling around the legs in the high overhead shot?

Good point on the shadow... Thinking about the side gun action in the overhead shot. I would say part of the problem with this is that the trail is too long. Side guns should be short rapid bursts of short trail lasers 1/4 size of main guns (or less) this would really differentiate them and make them make more sense rather than having the same effect as the "under the chin" big guns.

Because the trail is as long as the under the chin guns it shows up the angles a lot more. But the angle is correct the AT-AT just moved it's head.

What I find amazing is that so much has been altered yet we all all talking about really minor stuff it's a testament to the quality of that last clip.
