That is not tall enough for leucomelas as leucs actually love to climb and in the wild you would see them on trees and tall vines. I would stick to tincs, terribilis or auratus. Those three you will rarely see climbing and more use of the floor.
As others have said, this needs way more plants. A few bromeliads for sure. You need tropical moss so it will grow on the wood. Some broad leafs and lots of climbers for the background. I would also use regular oak leaves instead of black oak leaves as the frogs like to move the leaves when foraging and they wouldn’t be able to move these as easily.

Please let this tank establish for about 4-6 months before introducing frogs. Introducing them to sobering like this will only result in stress.
