TWT (his blog is here), who bundled it with some other stuff for me.
I painted it to approximately match the big heads I got from my aquarium shop. Basically greys dry-brushed with a mix of washes in brown, green and grey.
I can see this (and maybe others, hint, hint!) as a warning totem in a remote jungle, perhaps on Resurrection Island.
The mini was from What The? and is used for scale (with 30mm base).
Thanks a lot TWT - very much appreciated!
