Thanks you two! Yes, most of it is just my best guess judging from that one photo of what the rest of her might look like. That, and very good descriptions from relatives, which helped a lot. At minimum, she at least had to look convincingly human, and the rework helped there.

The smarter thing to do would have been to find a friend with similar bone structure and had her model for me. I had been studying faces like crazy all month in all of the meetings i have to attend during the week - looking for planes and junctures that are common to all faces, but slightly different on each. Recommend that everyone does that - it's a real eye opener (just don't let people catch you staring at them!)

LOL - Guilty! After doing a difficult portrait with poor references, I caught myself staring at certain types of mouths to get a better idea of facial construction.
Must have been very disconcerting for the poor store cashiers...
