I'm not sure I can add any brilliant comments from the ones you've already received...
Your play of light and shadow as well as dof are what make this shot interesting. Use of black and white and right angles makes the metalic, cold feel of the shot jump out. I think if the fore-most bars were crisper the feeling would be intensified and that would make the shot stronger (to those of us who liked the sterile feel the metal gives the viewer). Likewise a bigger difference between dark and light areas would intensify the impact.
Your eye for abstract composition is clearly shown here. Nicely done.
GREAT! like the lines and the s and the abstractness of this...totally cool and one of my favorites. I would like to see the front most of the rails straighter, but it is damn fine other than that.
Soft effect to the metal is interesting. Composition very good with matrix of the front rail covering the entire picture plane - supported also by calculated fit of the central focused short one. The back straight and angle pipe with dof creates an amazing back space to this. Really good. Congratulations. High mark for this.
I get a great sense of depth from this image. Well done with the DOF. The main vertical bar seems a bit too central therefore making the image seem a little unbalanced. Exposure is good. Not blowing the highlights on reflective surfaces can sometimes be a challenge. 7
