I feel like the shot is a little to dark on the right side and a little to bright on the left side.

I'm not sure if I would be able to fix this in post in a good way without making it seem unnatural.

Other than that maybe I applied a bit to much sharpening.

The exposure was for 1.6s with my hands resting on the railing of the bridge I was standing on. So the sharpening helped disguise any blur from shooting handheld.
