Nice HDR and light for a nostalgic effect. Love the muted colors. Good detail in the window too, but I wish I could see a bit more of the inside (as opposed to the building's reflection) as it seems there is a person working inside (but then again, I could be imagining it).
I'm at odds with the processing. I can't decide if it really enhances the image or is a distracting element unto itself. Also, the window is tilting in the opposite direction as the ground so everything looks askew.
