First man
I think he must be moody and short-tempered because the two parts of his face looks different and he has his eyes very closed together. His hair shows he is sensitive.
Second woman
She looks happy, she is smiling and seems a real smile, I can see a line around her eyes. She is cheerful and calm.
Second man
I can detect that his smile isn’t real it’s a false smile.
