I love the moss on the rocks and overall the look is really nice (from what I can see).
I would take the little gravel pond and plant it. Any rocks or bark chips or anything other than an organic fine soil that can be ingested accidentally when shooting for food could cause fatal impaction issues.
I would also add more vines and bigger plants. Vertical space that doesn't have a walkway is useless.
There is nothing wrong with an exo-terra. I moved my guy out his because he kept firing up at the glass (his reflection) and that constant stress is not good and it has been a nightmare keeping up RH ever since. Just watch your new little friend and make sure there are no reflections making him constantly mad.
What size is this tank? Can we see more pictures? I really do like the look and would like to see some more detail.
