So, for the last few days I've been working on figuring out good polygon flows for the face (well, the head in general, but concentrating on the face)

I was trying to take something anthro-ish, but had no specific animal in mind. Although, it looks a little like a mouse, so I'm thinking of running with that.

If this were a human head, I'd carry the polygon line from the corner of the mouth around the back of the head, and then branch another line off right in front of the ears. However, mouse ears tend to be higher up on the head, so I'm not sure what to do.
