This was a tough one... you want enough dof to have all the circles in focus, but not too much, so the building in the background would be really blurred... In this case I don't think you could have done better. I like the tone. I just wish the person standing by the car wasn't there... it's a bit distracting.

Great idea for a "circle" competition. I really like the continuous circles leading to the center of the circle. Good choice to switch to no color as the color would have distracted a lot in the background.
great tones. Love the contrast. Very approporiate image. Person on LHS is not quite a distraction nor focal point, though he is noticeable - might be better with him not there, or with him as a greater part of the subject. Still v nice.
