Well, I have drawn Morri's muscles, so I thought that maybe I could draw Iacar's skull as well.
This is by no means perfect or even accurate in any way, I just thought I could try to give his head some sort of inner design. And the moment I moved to draw his forehead I realised I should've drawn it from the other side of the face. Eyesockets are hard! Moreso if you don't know how to arrange them.
The upper skull is supposed to be normal dog/hound skull. I tried to get it look a bit wolvish, though I don't know how well I managed in it. I referenced from an anatomy book, where was a sketch of a dog skull and my own Yorric. I left the lower teeth undrawn since in the book the teeth were drawn pretty approximately and Yorric (my fox skull) doesn't have lower jaw.
I have once before drawn a skull of a pig, so I knew how to lift the ridge of the skull.
At least this gives some kind of idea of what's inside Iacar's head (and what kind of mess his teeth actually are). One thing I can say from this, though. Iacar must have pretty powerful jaw muscles. You don't want to get bitten by him.
Wurr (characters, story, world, scribblings) are (c) to me, thanks.
