What a gorgeous frog!! Glad to hear he ate!

Tank looks great to me, he could do with a little more cover from the sides, ideally you should cover the back and maybe the sides of the tank with some kind of background, like paper, to keep your frog from feeling exposed, or add a plant/fake fern for the same effect.
If the room gets natural light from a window there's probably no need to leave the lights on and you can cut down on misting by covering 2/3 of the top of the tank with plastic wrap, just to make things easier. ^^
If his eating stays slow after a month you could try blocking off about 1/2 of the tank, mine did better with less space oddly enough.
It would be good if you could get a digital thermometer, like the ones they sell for cooking, but for now it looks like he has enough room to cooldown/warm up as needed.

Sounds like their getting used to their new home!
