Nice work, but for me a tiny...mind you...tiny bit to dark, details are lost because of the darkness and I would have crop out that building on the left, cause it doesn't have a function in the picture.....in my humble opinion, ofcourse.
Rob, I am on the side choosing the darkness. I think it was a great tool to you in creating the atmosphere and moodiness of this piece. The cropping idea I am not too sure of. In a way, it sort of balances out the left side, gives you a border and anchor to the picture. If you cropped it out, you would have a different picture.
Nonetheless good angle and impressive sky!
