Well, if you combine our photos against yours, we tied! 
If I would not have had to vote for my own, #3, I would have voted for yours. REALLY nice sunset! Congratulations!
So tell us what your settings were.
My trusty 18-55 IS at 50mm, f/5.6, 1/250, ISO 100, handheld.
Straightened, cropped, and a slight play with levels to bring the orange out more.
Well done Bish! Interesting shot, what is it?
I have borrowed a picture from google to show something similar, but this is what I shot. It is a telescopis gas holder, google will be your friend here. As it moves up and down the ladders and stairs to upper levels remain, and that is what I picked out.
