I think it's pretty cool, and if there was some camera shake (and Derrel seems to be on the right track) I wouldn't enlarge and crop much because it's just getting worse.
I think framing slightly differently might have been better, but I might crop the left side a little. I don't know how well that would help because look at the long gray line created by the edge of the windows - it might be hard to get that looking better. I think shooting buildings that it helps to think about perspective and where you 'end' the shot along windows and doors etc. - the far left edge of the photo just adds chopped off blinds and a long angled vertical line that to me makes the picture seem crooked and throws the balance of the composition off. But it is framed straight I think looking at the smaller parking sign.
I notice too that the left side of the building that was closer to you looks more out of focus like that sign does, so maybe some of this out of focus affect might be the f stop and depth of field?
The fog is what helps make this a cool photo, that gives the light a more ethereal feel.
