Cover in terrarium

[UncleChester]

If money is tight, I would just look to add another hard perch high up to make use of the space on the left and more towards the front of your tank. Another branch/stick thing like you have or one of those mushroom ledges would be good, or even a piece of wood from outside (a good guide on doing this safely- Caudata Culture Articles - Wood in Vivaria). Your existing vine will eventually grow to give as much cover as you want.

Not that buying more plants would be a bad thing to do though
