Ignore me? I don't think that is necessary. I was the one who said it looked unnatural. It is my opinion, and you don't have to agree, but you should at least respect what others have to say.
I understand that natural ocean reefs have shelves of rock and coral, but I think that the shelf is too flat and uniform for a small environment like a tank. When I picture a rock shelf on a reef, I also picture the surrounding rock structure. This tank looks like it was a chunk out of a reef, which is a good thing, but in a tank I don't quite like the look of the structure on its own. However, if the tank were much larger, and the OP's current structure was surrounded by other rock structures, it'd look fine to me.
What I'm trying to say is I like the appearance of a tank that is a shrunken-down reef, rather than a piece of a full-size one. Does that at least make sense? I like the corals the OP has, but the rock structure isn't for me.
After all, the title literally says "what do you think?"
