This picture shows movement because the girl is twirling and dancing. The birds are flying to the left of her which is creating a lot of movement in the picture. This picture causes you to think about the birds flying and dancing.
It is so awesome to see how photo manipulation can work in a piece. I love how they made the explosion of smoke the same color as the body to really touch on the illusion of the face blowing up. It gives the image and uneasy feeling.
