It's allright. There's something in the frame at the top left that's bothersome. That can be cropped out (better yet, edited in Photoshop so you don't lose anything). Your sky is really bright too. Almost distracting.
It seems like you need something else in the image too

Like someone in a window because the only thing my eyes are looking at is the curve of the building (especially the top/roof portion) and that might just be me because I have a 'thing' for lines

Your image doesn't say 'roof' to me, it says 'looking up at a building'. Sometimes you need a story to make it appealing to people. Know what I mean?
In my opinion of course.
