Beautiful post processing with the duotone (and nice composition from the beginning). Not sure if this is the case or not, but it looks a little neat-imaged. I'd like to see a tiny bit of grit, but maybe that's not what you were going for here.
I like your photo and use of tonal values - it goes with the title. Being a bit nit-picky, I wonder how this would look if rotated jsut a bit (say .02 or .03) degrees counterclockwise. I keep tilting my head a bit when I look at, but again, that can be caused by the perspective angle. Overall, I like it. 8
