Only critique I would have is you have three points of equal height. That seems slightly unnatural. For my tastes, and to address your point about it being centralized, I may pull it apart into two structures. It seems there is a natural separation to the design, but I am viewing it in two dimensions of course. If you could pull it apart a little and change the angle of the left branches a tiny bit I dare say it would be perfect to my narrow eye.
I tend to like two structures, but yours is a great example right now of a single structure that works on many levels.
For fun, this is my aquascape in my 45 AIO
That is so pretty! Thank you!
Maybe that is what needs... My anemone is resting between two of the tall rocks in the middle, (can't see him in the pic) but I could move the tall rocks on the sides like you suggested. Agreed it looks unnatural. I do like the way he set up one of those larger rocks to be a flat out cropping that offers some shade underneath. I wouldn't have thought of that had I been setting it up by myself. I would loved suggestions on the best corals to add first.
