I got some time this weekend to work on the squiggoth some more and was able to check a few more details off the list. A big detail was getting the mouth done so I could put on the iron gob and not have to fuss with it any more.
The process was pretty straight forward with a layer of screaming skull followed by a wash of agrax earthshade. Then a dry brush of white scar. The gums were similar with a base of khorne red followed by a wash of agrax earthshade then some mild highlighting with Mephiston red.
Started the base as well which I think will compliment such a nice model quite well.
That's it for now, more updates to come!
