As mentioned above it doesn't look as though there are any hides for your snake... although it could take to burrowing or perhaps go Swiss Family "tree house" style it's also nice to have a small enclosed space on both sides of your viv. It could be as simple as running a paper towel tube along the length of the tank, or if you want to keep up with the "nature" look perhaps some store bought item.
Looks great, the cage is beautifully designed, just might want to find a way to create a few more hiding spots for your little guy.
