So I started working on my bone horrors last night, and noticed there is something that looks like a tree or set of thick vines flowing through the middle of the model. I haven't seen anything like it on the reference art or on any painted model I have found online (although that isn't surprising, the reference art is very different from the model).
I will post pics once I finish my set, but the easiest way to find it is to look for the spine along the back that isn't a straight spike, it has a little wave or bend to it, then follow that back down to the model and you will see veins like a climbing vine or tree running under the bones.... and of course once you see it, its everywhere.
Does anyone know what this is supposed to be? or have a reference picture or painted model showing it?
