The linework in this provides a great sense of direction and the different tones set the mood. I like the POV shots and the wide shots that set the location. Great detail on the faces too to convey emotion.
In this image, the blur of people moving around in the crowd makes it look interesting, but it is also focusing on particular people who are standing, walking, moving in what looks like a busy area. A slow shutter speed is used in this image.
