Just a probably worthless FYI. When I was involved with A/V equipment I learned that the way to test a really good mirror is to put an object right on the mirror like say an ink pen. If the reflection of the pen tip looks like it is directly touching the surface of the real pen you have a good mirror. If the reflection looks like it is standing slightly off from the real pen then you have a cheaper mirror. In A/V work the mirrors reflecting off of other mirrors and lenses need to be very precise.
I'm sorry I can't help you with the facial expression problem. I think I suffer from the same condition;)
