Your setup looks good.
I would reccomend though if your using a coil bub that u get rid of it. they are known for damaging chameleons eyes as im sure a lot of people will tell you the same. GLASS TERRARIUMS ARE FINE!! So many people on here rave about how you have to have a screen enclosure. There are articles on here from leading experts that swear that glass terrariums are just as good as screen and actually help to keep humidity up. you just have to remEmber to keep them clean so as not to harvest any bacteria. I personally use glass 60x60x100cm for 1 adult panther and have had no problems apart from 1 URI that was nothing to do with the terrarium, just me misting at night when i was a newbie.
I would get rid of the Hibiscus though, they dont seem to be able to tolerate heat too well and end up dying. I use pothos, although its not great with heat, it seems to last a while longer.
Hope ive been some help.
I forgot to mention, Id reccomend getting rid of the fogger too, its not good for the Cham. I think this may of been partly the reason for George getting a URI as it happened a week after using my fogger.
