Nice, glad to see he has a nice big cage. How old is he? You might have to cup feed him if he is still really little as he might not be able to find all the feeders in such a large cage.
I would add some horizontal branches for him throughout the cage. This way he can choose what temperature he wants to be at and just move to another branch to warm up or cool down.
Also, I would take the heat lamp off the top of the screen if you have it sitting on it. If he were to hang upside down it could cause a burn.
