Well done, Paul! It is nice to see an enclosure with a lot of natural elements.
What substrate did you go with? The only thing I would say, is be careful with the Tillandsia usneoides. I use it in my greenhouses with larger chameleons that don't try to climb on it. The smaller guys will try to climb it. I have used this in my own collection with smaller species and have seen them climbing on the plant and it separate and the chameleon fall.
That's the only thing I have to say about your viv. Just a cautionary opinion. Well done man and welcome to the Forums!
