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.
I love the shapes. The flowing fabrics and the strong lines of the dancers' bodies are a beautiful contrast, and all together they contort themselves into these organic shapes that are both graceful and powerful. Just begging for a sculpture!
