Bleeding blue, thanks very much for the compliments, I try my best. Usually I try to have things "offset but balanced". Like the main rock is to the right and a large structure, slightly higher and larger than anything else is the main focus, and even for corals I have the formosa right near the top and slightly to the right as to not be too centered. The best tip I can give is to do what you think looks good and in the smaller tanks, I think the "fruit stand" approach works quite well while in larger tanks I like the more open atmosphere. Here is an example pic of one side of my 40g, I tried to achieve a reef crest and overhand and the other side is lower and has a few overhangs as well.
