Looks good... just a few things:

Like LadyOhh said, you should get a UTH for heat from below. Snakes don't bask the same way lizards do, so they don't really need heat from above. Also, lamp heat sucks out moisture.

Cover the back and both sides with some opaque background to help the snake feel more secure...especially with only one hide. Getting two smaller hides, as you said, is a good goal.

Maybe add some greenery, like a soft fake vine, around those bare vines to lessen the open space in there.
