Congrats guys. Woot. Thrustage. Three cheers. A round of beers. All that stuff. The only thing I'd ask is, tell Raken that riding on top of Imperial Walkers without some kind of a safety harness is dangerous. His stuntman should have been doing that scene for him.
I don't see what the big problem is. If Raken wants to ride on walkers, he can ride on walkers -- he's dedicated.
The fact that you can tell it's really Raken and not a stuntman goes to show that Raken really wanted to make the scene realistic -- a stuntman would have ruined it. And you know it.
