When you use the words "right" or "left," we have to know where you were looking when you said them. I don't have a good grasp of your yard based on the pictures.

To be perfectly honest, the rockwork is not high quality or something that would be featured as a selling point in a resale. I would consider rethinking the whole concept from scratch. It's not clear what benefits you expect to have when finished, so that would be a great starting place. What would those be?
