Brass

Nice box of fittings that you have there, is it pneumatics or hydraulics? And there is the problem of this image already, I'm more interested in the subject(s) again. I do like it as a picture but it's not shouting abstract at me. I think you missed a chance there. You could have taken a score of each type out and arranged them regularly on a neutral background. Then take your fisheye and take a shot straight down at them. I bet that I would have liked that better...
