EYES: A person is generally said to have wide-set eyes if the distance between each eye is wider than an eye socket. Conversely, eyes that are "close together" are generally separated by a distance that is shorter in width than an eye socket.
NOSE: The nose can be changed with cosmetic surgery, but the distance between the bottom of the nose and the upper lip is unlikely to change.
MOUTH: Are both lips thick or thin? Not change unless a cosmetic surgery.
CHIN: Not change
EARS: Do they flare away from the head? Are they flat against the head? Are they large or small? Are the earlobes extra large?
CHEEKBONES: When these are prominent, they are a distinctive identity feature.
