Welcome to the forum. It's very nice to meet you. What types of frogs are you interested in? Arboreal, aquatic or terrestrial? The gravel/ pebble bottom is a concern unless you decide to keep smaller dart frogs, in which case I'd be prepared to put a few more plants in there for climbing/ hiding and some leaf litter on the ground. I love the stacked slate as well and the use of the broken flower pot.
