Shield Wall Sentinels - feedback appreciated


A new piece inspired by Frank Herbert’s novel Dune. The sandworm is supposed to be huge, so I’m using forced perspective, a touch of DoF defocus, and volume absorption to create atmospheric perspective, but I’m still not sure the scale is convincing, I’ve been looking at it too long. I want to get the layout and lighting pinned down before continuing with detailing. C & C always welcome.
