The focus of this challenge was one of perspective -- and the lack of some kind of ground (not literally) here keeps me from understanding what I'm looking at.
Very interesting shot of the machinery. Did the background get blown out (over exposed) in the camera, or during post-processing? If it weren't quite so bright, this would have received those extra couple of points from me.
I'm a sucker for anything that even smells of old-fashioned. Rust is a sure winner. I love this picture, and I love the way that it is framed, and I love the texture of it, and especially the coloring. Even a few little splotches of mold! Perfect. The "bowls" (I have no idea what this object is... some kind of dredging device, judging by the title) give a good sense of upward lift to the picture. I guess my only critiques are that the bowls seem too shadowed, and the grass to bleaches, especially in the lower portion of the photo. I know how difficult shooting in bright light, objects that are facing away from the sun is, so I won't dock you much for it, but perhaps that is an area where you could have really taken this challenge with ease. Otherwise, I still feel it is one of the strongest submissions in the field. Good job!
Looks like the contrast range in this photo was just too great for the time of day this was taken. The range from bright sunlight to dark metal was too much for this camera. Dawn or dusk might have been a better time to take this shot. Cool composition and very nice DOF though!!
