Seems like you did some good post processing with this. How you got the sky blacked out so good is unclear to me but the effect is good. It looks as though you may have "color burned" each brick in the wall, if not then your camera is "kick A*s".
The building does look a little "flat"....almost like a movie "front" but that does not bother me much. Overall very good. Since I did not yet see all the photo's, I can't say if this will ribbon. I'd say top 25 for sure...we'll see! 9
Not sure what you did to make the sky black, but it seems out of place. Overything looks well lit so it doesn't appear to be night, making the black sky seem totally fake and it doesn't seem to accent the subject much.
i understand the dark sky i just dont think it fits, maybe dark and cloudy. i think it might be the background trees. they might be to desaturated? i like the angle, but i think the original might have been a sunny day.
