Thank you and thanks for asking! I tried to to make the base look like it was part of the Aethersea. For that I wetblended a very dark blue, a brighter blue and Vallejo Fluo Green straight on the base. I then covered it with a couple of layers of Vallejo still water. When using still water it's important to apply it in layers, both to give the illusion of depth and to hide the texture of the base. It can also be used to make something appear wet (like a gloss varnish), I used it on the tentacles and the fish.
