Hey Wesley! These look great. I really like B and E. I like B because it is more simple and it seems like it would be easy to tell what is going on in the fight, if they are fighting there. B also looks more like an arena or stage. I think E is really cool from a design standpoint.. it's just more fun to look at. I might make the robot arms a little smaller, just so that they don't distract from the fighters, I think either design could work. I'm interested to hear what Dan/Ethan thinks , because I think part of their decision will be made on what makes a good challenge for the modelers or effects guys (if there will be a laser safety railing or whatnot).
