I like how everyone is on a different plane and only the one guy is looking at the camera. All that bright space above is distracting, though; maybe tilt the shot lower.
Makes me wonder what the three officers in the middle are looking at. In this shot, I think the stuff on the building providing the background is distracting. I think a more neurtral background would have been more appropriate for these police officers. Plus, you cut off some of their feet. This works being candid, but it bugs me..wanting to know what they are looking at. Thinking about it, however, to me, magazine cover shots are usually set up and not candid.
