Looks a bit too sparse to be hones ... maybe post all the info you can as I don't see many clues in the photos apart from what looks like a stick on plastic thermometer at the TOP of the tank ... those thermometers are basically useless and serve no real purpose in my opinion .
I'd read all the caresheets you can find as suggested by somebody already , it could certainly do with at least one more hide in there and any chance of sticking black paper or something on three sides of the tank ?
Also , maybe put some twigs and branches in there along side some fake , plastic foliage or pieces of dried bark .... it's just too open looking to make a young Royal feel secure .
What size bulb is used for heating and is it regulated by a thermostat ??
