Today I finished the rock parts of the Dreadfleet terrain:
I also painted the basing testers/experimental Nautilus submerged markers:
At this point I think I'm preferring the greenstuff water and the cutout marker, but I'm not deciding until I can sleep on it, and maybe get some feedback. I tried to paint in the shadow of the Nautilus in the rectangular marking, but it just isn't showing up clearly.
I do think I have found my water recipe, though. Just needs gloss varnishing.
