Hmmm....chair....I like it! It's random, but, to me at least, not overly so. It really helps to hide "Waldo" because my focus shifted...no that's not the right word....centered on the chair.
I really like the angle of this shot. Instead of looking straight down the alley, I like how the columns lead the eye to the right of the shot. It makes a very nice composition. 7
Why do you tell the voter where he is? You take away all the fun...
Nice composition. the green chair doesn't add anything to the image though. Your person is well hidden, you shouldn't have said where he is. 7.
