Wow! Really great shot! There is almost an optical illusion (until you scroll down, or eye gets down far enough to see the window on the bottom) that the building is rising on the left and right and you are looking straight out from a balcony. At first it just appears like an OK photo, but then the eye starts to decipher all the lines, most importantly those which frame the sky (great composition). This is one of my favorites that I have seen not only in this challenge, but overall. Good job!
