The focus seems to start on the second rail in the image (going from bottom to top). It looks a bit ditracting that the first rail is out of focus since that has the most detail in this image. Overall its very eye catching. The strong greens (was that the natural light?) really makes you look at the image.
Not sure if this would have enough in it to keep me coming back for more but as a first impact its a very strong image IMHO.
