Not too bad. I would move the lamp all the way to one deffinite side as to set up hot/cold sides. Believe it or not the placement of decoration and such can effect your temps and be used for a better temp differential. Cheap digital indoor outdoor temp/humidity combo from walmart would be alot better than the analog i must agree. Analogs read more of the glass temp than inside ambient so they can be way off and you'd never know. Some kind of uth control is very importantThe desert beckground is kinda funny but awsome start!
