Nice composition and sepia filter. However, I think the building is not parallel to the horizon, If you take a ruler out and place it on the roof top, it seems to tip downward towards the right side. This can be easily correct with photoshop CS2. Go to Filter-->Distort-->lens correction
Very nice b&w photograph, perhaps a tighter crop around the store would make a better impression. IMHO the space around and especially above the store do not add anything to the concept.
I think this one might have been more striking with tighter vertical crops at the left and right to draw focus more squarely on the very warmly illuminated shop. I might also have used a perspective crop to "straigten" the vantage (which appears a little crooked to the right). Overall, a 6 from me.
