Cool shot. I feel this wouldve been a much better picture if taken centered and looking up like you did in this shot except that the angle that you took here is a bit awkward. It shows more of the building on the right side and cuts some of the building on the left. A shot of the builiding evenly proportioned throughout would look great I think. Also, the sky a bit overexposed, maybe try shooting earlier or later in the day to avoid the harsh sunlight... All in all very nice idea!!
