Decent photo...with everyone's obsession with skies, I would have done some burning and doding in the clouds to add some added punch to the image. Good Luck.
Not so sure I like all that sky at top, a lot of empty space that does not add to the photo. Crop it out, focus more on the detail in the old building. There appears to be some wonderful textures there.
With many of these abondoned buildings I really think that the photos would have had a stronger impact in B&W. THis is one of them, especially with the clouds looking like they are about to drench the scene.
