Very nice!! I am glad to see you using a Ficus Benjamina. I think that is one of the best plants to use for chameleon enclosures. The only thing I will say is to be very cautious of the reptile lounger you have in the top right corner. I can see a chameleons nails getting stuck in the material. Nice enclosure though!!
I think your set up looks awesome! Lots of foliage for cover, and it just plain looks good! only suggestion would be possibly some more horizontal branches he can lounge/bask on up near his basking area so he can pick the perfect distance from the light for thermoregulation. As I'm typing this, I saw the post about the reptile hammock and maybe you could just swap out the hammock for some more branches? All intended as constructive observations, I think it looks very good!
