Everything looks great
The only suggestion I have is to keep your eye on the snake's behavior as his hide might be too big for him. Those half logs are really not a great hide for balls since they are rarely 'hidden' when they are in them!! If you find that he needs something smaller, you can use an inverted terra cotta (or plastic) planter bottom with a door or hole cut out for the ingress and egress. Just keep in mind that the smaller and darker hide can be- the better!!!
