Last night I played around a little and instead of laying down the small branch types I stood one up and it made all the difference in the world. I switched and put the big piece to the left 1/3 and stood up the one to the right 1/3 with the other laying down in the back giving it a concave appearance. The other advantage was I could rotate the wood so it opened up two cavities where I could plant some Bolbitus in.
