Oval eyes are the most uncommon, followed by closed (not squinty)... mohawk hair is the most desirable, but bald might be the rarest.

I believe sea green/spearmint should be uncommon. In my experience, that was the color I had the least of, probably because it was so similar to blue/teal that not many people used it.
