Yet another Head Study

Just a Stegosaurus with some kind of speculative soft tissue. Not going for fuzz or bristles this time - merely the old spiky and scaled Thagomizer-Owner you're used to. Or not?
Actually I have to commit it looks not exactly like the Stegosaurus I used to know as a kid. But those different sized and shaped scales along with bare skin are quite fitting also, I think.
Coincidentally John Conway seemed to have a similar idea with the plate-basis too, but to be honest, I had sketches of this before I saw his work. Some things seem to flow through.
