Hey guys, I need your help again :)
Please do critique this one, because I want to improve my skills.
What it shouldn't be in the picture, or crop, or what PP should I apply.

Thank you !

Very nice shot, Lovin! Can't think of any changes I would make to it!

I absolutely love the "copper" color of the bridge, rail, and lighting. Beautiful; however, 2/3rds of the photo is pure black of night. What about shooting this as a panorama so that it focuses more on the bridge, or shoot this bridge on a night with clouds? Seems like having SOO much of the photo being pure black is kind of a waste of space.
