I decided on the lower of the wooden block walls. The one with a L-shaped profile as it is more stable. I added the stone paper to the front and back.

I might add some paper to the top of the walls, depending on whether I go for earthworks added to the top. Then I’ll decide whether to add paper to the sides or just paint them.
