Honestly once you remove the vines, hes got like 2 sticks to play on, since the live plants are not robust enough to crawl on. id remove the cork bark (unless its for spousal approval factor) and put in a lot more sticks of various thicknesses.
Also GG on getting some air plants in there.
My cage moto is "if the cham is not crawling on it, adjust it or replace it"
