How to keep vivarium not looking like just a bunch of plants?

[flybyferns]

I have a vivarium that basically looks like a bunch of plants planted. There isn't really any depth or real focal point. What would give the vivarium a good focal point or add some good depth to improve its appeal to the eye? I have an exo terra background in it. I was thinking that maybe a large bromeliad would makeup for a focal point or maybe instead of adding diverse plants, just stick with one or two species...idk..please help.

Hi BettaShawn,
I think your enclosure is coming along quite nicely ! It's good to take your time.
As mentioned, it is important to consider what will be housed in the enclosure.
Have fun.
