First, no matter how much we may like a enclosure they are the final judge. What all lighting will you be using ?
I think it looks good with a nice amount of branches at different heights throughout the enclosure. I think I would remove the rope hammock, they serve no real purpose for chameleons. I have a post farther down the list "enclosure redo" with pictures of three of my enclosures that might give you a idea. All my enclosures are bare bottom for easier cleaning.
