Build up the substrate from left back (high) to right front(low), use all the short rocks, tight against each other, to form an open (to the front) horseshoe on the slope. Use the large rock on its side in the back right as a retaining wall and build a terrace.
Hairgrass in the horseshoe, something frilly behind it, maybe a mix of red and greens (reds toward the center of the tank), Crypts up on the terrace, microsword in the foreground outside of the horseshoe.
Not that I have an eye for aquascaping mind you.
Aquascape? I'm a crypt farmer.
It's a fine line between fishing and standing on the shore looking like an idiot.
That IS an aquascape, it's titled "The Vacant Lot".
