good sense of form you got with that light source that seems to be some kind of window, i like the color changes on the top, those greens look good. Very interesting subject matter.
Please, even if you don't visit my gallery, check out my "Faves".I've left them intact since day "1", and would like it if every image there got the attention they deserved.
I love being shown something that I might pass over while walking through. Low light, Rust, and the patina of age are high on my list too. I'm really hit by the light in this one. Notice that the light falls directly on the subjects faces and falls diagonally from light to near black. Love it.
