It’s a nice start the nose looks oddly flat thought you might want to do something with it. I’m reminded of a tube sock that I have just taken off kind of limp and sweaty. It might be the coloring to it needs do be a little more on the rich side, to help distinguish it from the rest of the face. Or a little more on the pail side, this is because he will have blood vessels closer to the surface of his skin in that area also in the cheeks but not so much the jaw or forehead.
Can’t wait to see what else your going to do with it.
