It is looking good! The only things that I would suggest is a few more branches, 4 tree frogs are going to need more space than just 1 bar to share. The other thing you might want to consider adding eventually is a drainage layer of hydroton for your plants, that will help prevent root rot. Someone on here told me once, if it looks like you have too many plants, then you have enough. Keep adding and watching them grow, eventually it's going to look super fantastic.
