Hi there.

I hate to be the one to rain on your parade, but I’m going to. While that is a truly lovely looking enclosure, unfortunately it needs lots of changes for a cham...especially a veiled. While the glass with proper air venting is fine, that one is much too short. Chams are arboreal and like height and being able to look down upon the world. The best/minimum size for most chams is a 24x24x48.
The dual dome won’t be able to provide adequate uvb. The recommended uvb is a T5 ho linear (long) fixture with a 5% bulb as long as the width of the enclosure. You can use the dual dome for basking light and a plant light.
While I love all of the moss and similar and fake plants are easy, veileds are plant eaters. They may eat the moss and a fake leaf and get impacted, which can kill them, or if you’re lucky a very expensive vet bill. It is best to use safe real plants and no bottom substrate. Bare floor is safest and so easy to keep clean. You’ll also want to figure out a drainage system for all the excess water as standing water is a bacterial breeding ground. Safe and easy plants are Pothos, schefflera, hibiscus, wandering Jew and philodendron. Pothos is my personal favorite as it quickly grows some nice vines that offer more climbing and hiding opportunities for my chams. Speaking of, you will want to add many more sticks and vines for your cham to climb. Avoid coniferous branches like pine etc.
Not sure what the little dish is for. If for water, you won’t need it. Chams only drink water from leaves, so you’ll either need a spray bottle or a misting system.
You really have created a beautiful enclosure...just not for a cham. Perhaps a crested gecko would do very well in it.
One last thing, if you get a female veiled, she will need a lay bin in the enclosure. Is easiest to just keep it in there all the time rather than guessing when she’ll need it. Whether mated or not, she will lay eggs like chickens do.
Hope this helps.
