Does your Cham use the little Chair?

Looks really good, but if I would critique anything it would be that most of the branches are at 45 degrees or so. I may be wrong, but Chams typically like horizontal branches. I'm betting you did the branches the way you did for the same reason I did, to give your cham a path to go from place to place. I would only add a few extra horizontal branches towards the top to give more level crawling space. (just below the horizontal vine like in the basking area.)
Be sure to check temps at the highest point. How are you going to control or add humidity?
