Thanks! The trick I guess it getting them to look good long term. This tank needs one more sand pool somewhere to even out the tank because it already has two focal points. I can only sort of break those rules because there is so much focal point (Like a jungle tank but with rocks), and because I now have that rock foreground. ... but two sand pools as well is just too even. It needs a third I think.
You're right. The flow of the branches pulls my eyes left to right. Maybe you can make another one in the lower right hand corner. A big one the covers the right lower side could look good or a small one that you would have to make with more rocks.
