It looks like your setup is pretty good.
I've kept a few of those over the years with success. Temp gradient is important. It needs to be hot enough that they can't stay in the basking area for hours. I forget the temp but I think the bask was over 105. I let them get cool at night (high 60's). They are active with predictable habits...an observant keeper can make adjustments pretty easy.
Big appetites with variety. Collard greens. mustard greens. grapes. bugs.
I used a cricket enclosure. Buy the crickets and put them in the cricket enclosure with a good variety of fruits/veggies dusted with minerals. This allows them to fill their guts with good stuff before you feed them to the cham.
Only put enough bugs in the enclosure that he will eat them all. They don't like bugs walking on them.
They do best if you handle very little.
