Facial Expression.

Again I have drew facial expression but these I do more every second of the day. Bottom right is a normal look wondering beyond the mind what the person is actually thinking and I normally get asked what I'm thinking about when I use this facial  expression.
The top drawing is used for angry, annoyed and confused. This expression is my evil stare, some times I really don't know I am doing it, it just happens.
The left drawing is a sad and depressing look, not crying but hiding away for the unhappiness which the mind it thinking.
I haven't drawn the mouth because I wanted to just focus on the eyes and nose area to practice the style of drawings.
