Here's what it looks like on the model.

I did some experimenting and will have another go at closing that gap in the middle of the face. I can get something fairly reasonable if I cut only the underside of the chin, which should be a fairly harmless position for a seam. The tip of the nose will have a bit too much stretching for my taste, but maybe that's not quite as bad as having the lips cut in half. I will however have to do some more manual adjusting than UVLayout lets me do comfortably. I"m not sure whether I'm reading the manual wrong or need the pro version for that kind of thing. Anyway, off to learn Roadkill and possibly Blender.
