As a size comparison, here's a pic of the Burrower fighting the Sumo, which is still WIP. The gaps on the models' sides are enormous. I filled them in with Apoxie, but not all the way up since the belly has a different texture than the back anyway and they are nicely separated this way. The model looks completely different than on the data sheet anyway, there it is just a round worm like the Cthonian from Mansions of Madness.
