Welcome! You have a good start and a nice looking american green tree frog there. The LED is fine for your frog and will make your plants happy. Your frog doesn't look too skinny judging by that picture, make sure you're dusting with calcium and vitamins in addition to gutloading so that your frog is getting the nutrients it needs.

How big is the tank?

That is a lot of moss in there, I'd be concerned about your frog getting a big mouthful of it. I would consider bowl feeding, that way the crickets cannot hide in the moss and your frog will not eat the moss by accident.

Make sure to get a lot of branches in there, make it like a "tree." Your frog is a tree frog after all, and want's to dwell in the vertical space.
