I dont mind the un-natural look, i like the look as it is, i just want to make sure there won't be to much territory fighting
but the main idea of rockwork is to make caves and 'comfy spots' for all the fish, and you have accomplished that well.
There is a good amount of caves, if that is what you want to know; but IMHO, the rockwork looks to me too symmetrical and then, a little bit unnatural. I would create 2 piles (one on each side), one bigger than the other. The bigger one should be larger and higher (more than half of the tank's height). In the middle of both piles, you can put a few dispersed rocks or very low caves for decorative purpose. Of course, this is just my opinion.
