NYC Chinatown

This was taken in New York's Chinatown

I like street pictures like this a lot. Most people try to isolate a single scene but I believe showing a busy street like this and giving the viewer a choice what to zoom in on is a viable alternative. Here the people in the background are the most likely centres of interest, because they are the only ones looking in our direction, especially the two guys on the right. Unfortunately they are not sharp.

The picture really falls off in quality at the right edge... not good. Who/what is the real subject of this shot as it's not clear?
