Who am I?

I’d love to know what sort of situation / role you would associate with these different shots by the excellent David Ho of Headshots Scotland:

1 (side look)

2 (direct, smiling)

3 (laughing)

4 (smile with tilt to head)

5 (slight angle)

Considering the above as 1 (side look), 2 (direct, smiling), 3 (laughing), 4 (smile with tilt to head) and 5 (slight angle), what do you think? Which image expresses what for you?
