Hello,
There's a few things I notice from your pictures;
She looks WAY too close to the heat bulb. The white spot looks like a burn mark. Which would be caused by her being way too close to the heat bulb. A
Minimum distance would be like six inches away, With all of mine I keep the bulb at least 8"-10" away with a 60W floodlight and it gets the job done well. Any closer And there could be risks of overheating and burns.
So now, I'd say your setup is really nice and you've got a good start, but I would suggest lowering the basking platform down a bit or raising the bulb higher and away from the tank via a stand or something. You also need to find a way to rig the
UVB bulb underneath the screen as screens block 40% of the UVB that is being output. Which is not good.
You can ask almost any of the regular/veteran posters here and they'll show you some ways how to rig it under your screen. What I do is go to the dollar store, get some chenille stems/pipe cleaners and use those to poke them through the screen and hold up the fixture like this:

Also is the substrate you're using A loose particle substrate like sand or walnut shell or something? Or is it a solid substrate like paper towels, tile, or carpet?
She does also look rather bloated or swollen on her side, which is concerning combined with the not eating. I would suggest a visit to an EXOTIC reptile vet (not the usual cat or dog vets) to check out the bloating.
