Wow what a drastic angle, you nailed the perspective idea. The lines are absolutely amazing the way they just pop off of the image. I also love the coloring you have used. The sky looks great in contrast to the dramatic building. I too like some of the other commentators would have liked to see the tip of building as well. I can see you wanted to consume the photo with the building which is great, but I still think the tip would complete the photo. The composition and lighting are lovely. Good job capturing such a dramatic angle.
