I agree about the crop. You might also consider a slightly wider aperture. I've read that, with digital sensors at least, an aperture over 9.0 or so can actually reduce sharpness.
If you do revisit the scene, maybe go at a time when the sun isn't casting shadows on the building too?
Well, I found another image that I have cropped to address various concerns but this is my last submission. Thanks for all the suggestions.
