This is pretty incredible, thanks so much for choosing my photo! Congrats to the other winners as well!
And yes, the photo was taken on the Skydeck at Sears/Willis Tower in Chicago. Got lucky and caught the girl alone in the window, normally the windows are full of people. The photo was taken with a Canon 5D and 17-40mm f/4L lens for those interested.
Congratson a great capture, the photo looks awesome.
