According personologists:
The first woman has thick lips, her hair is quite fine and the two sides of her face are similar. She's talkative, sensitive, emotional. He is probably calm and cheerful person too.
The second photograph shows a man with long upper lips, thick hair and the two sides of his face are not very similar. He's probably sarcastic, unemotional and sometimes maybe he could be moody.
The third person shows a real and beautiful smile. She has her face very balanced. I believe she's calm and cheerful but her lips don't look very thick. She isn't probably very talkative.
The man of last one is difficult to describe. He can be sarcastic and unemotional. But he looks cheerful. Particularly, I believe he is a little vain and selfish.
