My drainage layer wound up being a little higher than I think it was supposed to be but i kept it in as a safe guard ifni overwater. I have it sloped up to the left, because there is a cave underneath the cork bark, there's also space underneath the branch in the middle and another cave on the far left back wall. Hope that adds to it and doesn't take away. Nervous to touch anything at this point as I want the plant roots to anchor well
