I'm not set on anything necessarily. And I know it's my tank but I do want to have a more natural look and I'm an engineer so natural tends not to be my thingReversing the wood has made me look at this a bit differently. I will offer my thoughts, they may give you ideas or rethinking, in the end it is your tank. I have a basic desire to always go "nature" with wood, rock, plants in an aquarium.
I think the little piles of rocks/pebbles around the branch ends are really artificial, made moreso by there not being rocks anywhere else.
The shape of the wood now concerns me, and if I had this I would try it in every possible placement. One that might work more naturally is to have the branches sticking out into the water at an angle. The main "stem" might look better if it was sort of "held" by rocks at the back. Hard to put into words. I'll see if I can find some photos from my tanks to illustrate.
