Snowy Ascent

I've always loved these stairs, but had never found a composition I liked, or found the composition but never the right light for contrast. Finally, with the help of some snow, I found the image I've been waiting for. This was made with a Canon 5D and Makinon 28mm f/2.8 lens at f/5.6. This photo is more urbanscape than architecture, but I think this would be the most applicable forum. I know of some things would improve the image, that I've chosen to leave for feel or because I don't have enough faith in my photoshopping, but I'd like to hear your thoughts on it.
