I love how you took something ordinary and turned it into something that people take a second look at. Not only the creative angle, but the colors as well. Like how the colors are more vivid in the reflection of the building. The cloud in the top left corner draws attention because of its brightness. I'd say that's probably the focus point of the entire thing, differing from the common 'center' focus point.
Hopefully this isn't skewed by my fascination of tall buildings like this, considering I've lived in a small town my whole life and buildings like this don't exist. Regardless, I think it's still a great shot.
