I was thinking about adding the under-chin part to the neck. It would probably fit quite well and make for better placed seams. I thought it was neat to have the seams at the group boundary between head and neck, but that's probably only useful in special circumstances.

Not quite sure about the hairline thing. Maybe I'll try to find some references and see how much I'd have to change the topology. I did go a bit further than the hairline with the face map because it will typically have higher resolution, and for bald heads or unusual hair styles it's probably not good to have those seams too low on the forehead.
