Looks great! I’m a student of aquascape theory at this point. But that does look the best so far. One thing I’ve thought about while planning my build is what corals am I planning on keeping? In my case I want a true mixed reef with sps, lps, and some softies. So I’m thinking three levels so to speak.
I think you're 9/10 of the way there. I would remove the top rocks on the right hand side - those look odd to me. And I think having that pointy rock as your peak would look cooler. Overall looks great though.
