Looks like an ok setup except for the substrate and the temp/humidity gauges. Get that Accurite gauge, set it up on the cool end, and put the probe over the hot spot (just kinda bury it a little in the substrate so it stays in place). Replace the white crap with some cypress mulch, coco husk, eco earth, or a mixture of those. Cover the screen top with some plastic or something similar......I'd do both ends and keep the center open for the heat lamps. Doing all of these things should result in a pretty decent viv. Just be sure to keep an eye on the temps and adjust the wattage of the bulbs and/or distance above the cage. Misting should keep the humidity at the correct levels as well.
