Thanks for you comment Armando.
Akira, I have attached the edit with the pier in the middle. Because the previous version was a bit off centre, there was a slight tension. You are right, the lack of tension does add to the surreal quality. Thanks again for your comments.
Peter, thank you for your kind words.
I never noticed where the light was cropped. I have cropped it a bit lower which looks better. After reading your comment, I noticed that the first pillar of the railing is also cropped in the middle, and as a result it appears to be hanging in mid air! Its interesting how one can overlook problems even after looking at an image many times. It definitely helps to have others look as well.
