Beautiful colors and a veiled is a great choice! Make sure to load that enclosure up with lots of live plants so he can hide and he will be a happy guy!
Here is the veiled chameleon care sheet from the Chameleon Academy which provides an example of the “forest edge” style.
They need places to hide so they feel safe and comfortable. You should only see him when HE wants to be seen. Live pothos plants are really cheap and I suggest you buy mature ones with hanging vines. If you’re in the US, any local big box store like Home Depot or Lowe’s will have them. Or just get them online. If you need references I can provide them. I got an amazing Hawaiian pothos off Etsy.
