I have done this shot before but always at night and in a vertical orientation. I had been thinking it would be cool at blue hour so I made sure to make a stop here when the time came. I went with a horizontal framing this time, which I think I prefer now that I am seeing the results. I shot this with my Nikon 70-200 2.8 @ F3.5. I blended two shots together for this one though the second shot was only for the highlights on the tower sign and lights on the right hand side. The blue of the twilight hour really helps to compliment the purples and greens in the scene.
