Jeez - those surrounds don't give you much to work with do they!
I can see what you were going for in these but they're not quite working for me as is if I'm honest, but good for a first exploration of what looks like a bloody tricky subject!
#1, maybe if it was shot from off to the left to give the bridge more of the frame to arc into, and having moved forward a bit to not have the black street-lamp in the immediate foreground. Bit much space, not enough bridge/features as is IMO.
#2 is close, but there's a bit much foreground space for my taste. Point the lens up some more, let those lines under the bridge sing a little louder, ever if it converges the verticals. It'll also emphasise the curve more...
#3 with a crop that trims the R/H and bottom frame until the foreground rocks and light reflection should be shmicko.
Those are just my thoughts and would tailor it more to how I'd shoot it, but everyone sees things differently, so take it with a grain of salt!
