This is a wonderful candid capture. I like that everyone is facing the camera and the lighting for the walking people is quite nice. I might like more light on the foreground couple seated, but an excellent urban shot.
I like the overall capture and the use of the B & W. Focus very clear. I would have straightened the image probably. The "opposites" concept isn't fully realized for me.
I like the composition with people in motion. It's too bad the face of the man sitting to the right is dark. That's difficult to correct with the Basic editing requirements
I like the shot, but is it kosher to use a black and white picture with no additional redeeming black and white subtext to illustrate a black and white challenge?
