I think the person of the first photo is talkative because she has thik lips. Her two parts of her face are balanced, so she is calm and cheerful.
She has also fine hair, so she is sensitive too.
The second photo shows a person with thik lips, that is ,talkative. Unemotional ,because he has thik hair ,and calm and cheerfull because his two parts of his face are balanced .
In the third photo we can see a false smile. It doesn´t appear any wrinkle in her eyes.
And the last man I think is short tempered because his eyes are together.
Do you agree?
