The best thing I've learned about Aquascaping is twofold: keep as much open water as possible, and provide as much surface area for corals. By this I mean like a bonsai inspired aquascape, something minimalistic, yet provides lots of room. Try to limit points of overlapping in your liverock.
The picture I've attached is a great example, however it is not mine. I'll try and post mine soon.
Lastly, it really doesn't matter what your live rock looks like when your corals are huge and dominate the tank! Just have fun with it and see how it goes.
