I wish I had a sopt in my home for a custom enclosure like that....its NICE!
Out of curiosity whats under the carpet??
He does look "thicker" which is great as well.
One thing to remember......Even though he seems to be "puppy tame" use extreme caution when letting him roam free around the house when your son is home. The last thing you want is the snake getting "spooked" by a quick movement and biting (or worse) your son.
