The above image is of an angry or frustrated man. His eyes are quite tight and squinted and his brows are furrowed. Once again, his mouth is parted and his teeth are clenched, as though he is trying to keep his emotions inside due to the fact that he does not want to make a fool of himself, or he may not be able to express his emotions at that point or place in time. His hair is quite scruffy and messy and his hands are clenched in tight fists.
