I really like this picture, and that's why I picked it for composition. It has lots of movement from the colors, and a lot of good negative space. It also is a little bit off balance, which makes it good composition.
This picture is a good example of movement because the artist pulls your attention to the tears. To start you look into the pupil and see the man in the umbrella, but then you see the tears and it makes me think she is crying seeing the man walk away.
