Looks great. That cabinet's going to be a very convenient place to keep your supplies. I'm a little envious.
Another addition for you to consider, a camera. I mentioned, previously, that your snake isn't going to be very active. When he is active, he'll be most active at night. A timelapse camera will allow you to capture this activity. That it has a timelapse feature is important. You don't want to have to search through hours of video. In the linked video, I can review 8 hours of activity in 1 minute. It also needs to be able to film in the dark. They are not expensive either.
Ooh a camera is a great idea! Add that to the shopping list lol
