Nice setup. I've never had any harm with pimping out my tank when its on the large side; usually my snakes are just fine coiled up in their hides and don't have a reaction to all the fancy things. Be sure there's not too much clutter to prevent your BP from stretching out comfortably (but with a tank that huge it shouldn't be an issue!)

Either it's my eyesight or my laptop screen, but what substrate are you using exactly? I can't seem to tell.
