Hi and welcome! And already a big thumbs up for the work you've done so far and most importantly by doing this in advance. Most people buy first the chameleon and do the rest later!
For now 2 things; it looks like there's fake plant in behind, just remove it, no artificial plants are recommended. And removing it now, than causing stress later on when the cham is already in it.
As building it's great and will work, I would only at now lots of different sized branches and twigs. If you have garden with (hardwood) trees in it you can it from there, if you don't use pesticides. Just rinse them with water and them dry in the sun. Stuff the enclosure with it, general rule is every square inch of air is one unused for the chams benefit

Especially if it's a baby use lots of thin twigs to ensure they have full grip.
If you would like maximum and full range feedback, I would recommend filling out following form and the more knowledgeable members will give feedback to get your husbandry spot on for your beautiful baby. Once again you're doing great already and this just the icing on the cake.
