I've put the finishing touches on the Stormvermin Champion last night, and painted the base. The base was covered in sand, and painted with slightly thinned Graveyard Earth. When that was dry, the sand was drybrushed with Bubonic Brown followed by Bleached Bone.
I'm pleased with the results and its another model finished. I'm planning on adding two different types of static grass, the standard short fibers that you can get at GF9 and a longer set of darker fibers.
