That is a very nice looking set up
Nice and spacious, and very well furnished

You may or may not already know this but the issue things as as repti-carpet or the carpet you're using is that because of the solid surface area and the porous nature, it will harbor bacteria like there's no tomorrow. Even if you frequently rotate and clean the carpet, moisture and humidity will sink deep into the surface and with heat, will present the IDEAL conditions for the nastiest type of stuff to grow in. If you chose to consider it, I would recommend switching to some form of substrate (not sand, which is what I originally thought you had in there) such as aspen, cypress mulch and several others.

If you're looking for a cheap supply of aspen, there's a company called Sun Seed that makes dust-free shredded aspen. It comes in a value size called the 'Press Pak 3200'. It's compressed volume is 1250 CU IN and expands to 3,125 CU IN. I get it a pet store for $11CAD. It lasts me just over 2 months for one 20 Gallon tank, regular spot cleaning and fully renewed substrate. They normally make it for rabbits and small rodents but it's super money efficient as apposed to buying "reptile specific" substrate in a quarter of the size.
