Great image! Two suggestions: maybe post process it to be darker and more sinister, to give a sense of impending doom, and maybe try cutting a bit more off on the bottom to isolate the subjects more, as they are both on the top half of the photo.

I like how the curved tracks take my eye to the subjects. Nicely done.

Cool shot! If you ever photograph Turcot Yards give me a shout and I will post your work on my blog, Walking Turcot Yards. http://neath.wordpress.com
