Looks good so far! At first the smile looked a little too happy for a demon, but when I looked at it longer, I can see evil in that smile. I like the asymetry of the expression. In my opinion, the concavity of the forhead above the browline is a little too much, though I know we’re talking demon here, and not human. I think the brows are a little high so far, making the eyes a little too innocent.
I like the way his ears are kind of normal in proportion, while other features are exaggerated. Im mentioning the ears because something made me think you might enlarge the ears to make them match the chin and nose, but I hope you dont… I love their proportion, and I cant wait to see them with some more anatomy carved into them.
What app did you do the base mesh in btw?
