This is a nice image. I like the fact that you shot this in black and white. I also like the fact that there are a lot of curved lines seen in the wall. Nice work.
Nothing in this photo would suggest to me that the building is abandoned. It does look old and historic but not abandoned. The picture is fairly crisp and the dimensions you have chosen for the photo fit it well. Good luck in this challenge.
Interesting building. Too bad the plaque was there. I like the contrasting textures between the rocks and the columns. The light pole in the back detracts, but maybe after the challenge you can clone it out. I also think upping the contrast in tones may help - make the blacks a little blacker and the whites a little whiter. It would really add drama to this image.
