Looks like he may have a smaller hide on the right side, but that could just be a rock. My only suggestion to that would be to make sure there is a hide above the UTH / Under the heat lamp for a warm spot hide.
Looks like the snake can hide under the plants as they provide a lot of hiding space for the cooler side.
One last bit of advice is to monitor the humidity as it may get too high depending on where the terrarium is located. The terrarium in my basement maintains a consistent 50% without the need to mist or cover anything.
