Very nice! Do make sure that climbing limb is secure and won't flip or tip when the young boa climbs it. Goes without saying that you check the lid and add extra lid clips if it's got any "give" to it. Boas do like to nose around and even young ones are strong and determined enough to shift a lid that's not completely secure. We used a 40 breeder tank for our son's young male boa and bought black metal lid clips when we noticed Severus pushing on the lid. Boas are very quick about figuring out how their homes open.

Congrats on getting a boa. They are truly fun snakes to live with and if properly socialized as young snakes tend to make a great scaley buddy.
