The toadstool is the the thing that got my attention immediately but it's right in thr middle of the tank. If you move it somewhere else it will also open up that area.
I would try to make the 2 sides of the tank more different, by moving some rock from one side to the other.
If you manage not to split the tank right in thr middle, even better.
