My thoughts on the image: I tend to agree with most of your commenters here in that this is a fairly uninteresting composition. The centered yet awkwardly tilted building leaves me with an feeling that this was more of a snapshot that an intentionally composed image. I do find that the building appears to hold a great deal of interest, and I think the composition possibilities here are near limitless.
My ideas for improvement: Put more time into the initial composition of the capture. I am not sure if tighter or wider would be better with this one, but I'd like to see combinations of both. While I am no stickler for the 'rules' of photography, this particular structure presents with far to many possibilities to be closed in with a centered composition. I'd also like to see more contrast to the overall image. Perhaps shooting this one at a different time of day would have presented you with some great shadows and more highlights that the flatness that this particular lighting yielded.
Where I would have/did score this entry: I did vote in this challenge, and you pulled a 5 from me. I do think that it meets the challenge perfectly, but with some better execution and composition, this vote would surely have grown.
Thank you for the opportunity to provide a critique on your entry,
