Usually, when you cover half of a person’s face, you find the’re a “good” half and an “evil” half. Try it with Edwards. They’re both evil.
Is the sinister side usually the bad side?
I have read about what you talked about in the past and have tried it on some pictures, it seems to be true. Of course no one's face is exactly symmetrical.
On another note, I never realized that the word "symmetrical" had two "m"s in it. Good old spell check caught it for me.
