Hi blurrblurr. Welcome to APAD.
Your picture is a nice attempt to shoot a building differently. However, as it is, the image is a little too flat for my liking, i.e. don't feel that the black circumference, the building and the sky are in distinctive area, but blend altogether like on a flat piece of paper. Leave it as it is, if you prefer to represent it that way. If not, you could perhaps increase a bit of contrast, by either playing around with the saturation of the sky and or play around with the contrast and lightness settings.
Snapsnap posted a similar (but IMO, better) shot in his APAD recently as well. You may wanna refer to it to see how to improve on your shot.
A minor note, the circumference in the foreground isn't whole. The building at the top left hand corner is just too distracting in my books.
