Interesting subject, but perhaps a much tighter crop on the subject to get rid of the messy and distracting greenery on the left, bottom and right sides.
What a perfect subject for this challenge and I like your choice of black and white. I am not sure the straight on viewpoint and centred composition are the strongest choices and it might be nice to have some cloud detail to the sky but those are minor suggestions. A really strong fit to challenge theme.

Would this work better if the collapsed roof would have been more in the outer third of the picture. The sky also cuts the picture in half. It might have been better to have more ground and less sky. These are just some thought to think about. I like the lightiing and feeling of this photo.
I like this, but it's a little too centered. Also, I think the lighting is too bright for the subject matter - a darker look and/or more contrast would make this more dramatic.
