More corrosion cast blood vessels

This time,  they're on the skull.  These blood vessels are so much fun!  They're also dead easy.  They're just paper mache snakes which are painted and glued into shape.

I've also added horn armatures as you can see, which should explain why the teeth aren't shaped like normal human teeth.  Eventually the skull will get a coat of polyurethane, which will improve the look of it, but that'll probably happen after I do the skin so that I can just go over with a big brush and shellac the lot in one go.
