Looks good I would recommend different hides and I would also recommend covering 3 sides of the tank with something to block out light and line of sight. One of my snakes was a problem feeder until I surrounded 3 sides with aquarium background. Blacking out 3 sides will make him feel more secure and a less stress to you new little guy here is a pic of what I am talking about
I also made some nice tight fitting hides out of flower pots in the photo hope this all helps
