Shame no one is looking at the camera. With everyone's back to me I have a hard time engaging myself into the image. I see the brick and everything, but even as a documentary shot, it falls short. Eyes, faces, expressions, will help your viewer connect. Wait for something to happen that pulls you in, and then you'll pull the viewer in as well.
I would hope with you this close that this was a training exercise and that you and your camera weren't in danger of flying bricks! Excellent constrast and detail in this conversion.
nice photojournalistic street shot! I would have loved a different angle to include the brick throwers in the shot as well, but that's not always possible I know. : )
6- I'd like a tighter crop in on the subject, the rest of the guys i find rather distracting, I do like the stopped motion however hear, and a added feel of emotion from that.
