i give it a C- for 3 reasons
1. Correct me if i'm wrong but you are using a compact bulb as your UV light? if so, this gives little to no UV rays to your dragon. Reptisun HO T5 10.0 uv tube light is a better bet, you can find it and the fixture on amazon.
2. It's a nice cage (cool hammock) but I recommend getting a larger cage for him to move around in in the near future. You can build your own out of plywood or buy one online
3. Even though you said don't mention it, it doesn't negate the fact that your beardy could lick the sand and potentially eat something that got on the wrong side. I wouldn't risk it personally
