Does she have any hides? She should have one on the cool side and the hot side plus a moist one in between. Most people use a Tupperware container with a hole cut in the side with some damp paper towels or coconut husk. How do you provide heat?
Awesome! The only thing I personally would change is the substrate. Leos like to lick everything and loose substrate could cause impaction plus it's messy. Tile is a nice looking, easy to clean alternative.
