The look
Eyes can say much more than words. A look can be absorbed even before the person speaks. Samantha, (There’s a picture of her in this blog.) has these amazing eyes that look right through you. She does not talk much but stares and barks when annoyed. Her eyes do all of the heavy lifting.
Capture your look by using the eyes to obtain the effect you desire like effective actors, politicians and business people do. Joy, disappointment, sadness, authenticity and dishonesty and most other emotions are first reflected in the eyes. A good way to learn about the eyes is by watching films, live theatre and television programs.
