Countenance, yes. Features, no. Some of the kindest people I ever met were not attractive at all by the world's standards.
I don't know, but from my experience, there was usually a very strong correlation between a person's attractiveness and their personality. Perhaps because they were treated so well, the pretty girls were usually very kind. The ugly ones, on the other hand, had lots of bitterness inside and it emanated. This wasn't universally true; I've seen several very kind ugly people, and even fewer nasty hotties, but that's my experience.
