My gawd.
You have put a LOT of work in!

My only suggestion would be to move the holes to one side of the hide (not on the side itself, but to the right or left side of the front rather than in the middle). When openings are in the middle, more light gets in. I find that snakes don't like that so much...

Beautiful stuff though! Very interesting. I made something similar for my corn snake using two Kleenex boxes. But I twist-tied them together at the sides, and had an interconnecting hole in the middle of the two. She LOVED IT. So much so, in fact, that she plugged up the top part of the hide with aspen and I couldn't get her out. I didn't see her for like a month. LOL (she ate of course).

All the best!
