Celestial faces

[Bluetoes101]

I'm spending a little time on this tonight. I feel like there's at least some possibility something like this could be intended. I'm ignoring the whole sun thing for now, and just focusing on the head. I feel like the key things which are not taken into account by an assumption it is a fillet over hair, is the top and bottom detail - as noted by Diane. 

I feel like something like this, or variation including a fillet could be plausible. Looking at/for manuscripts with examples of this sort of thing currently.
