I like the B&W toning here, because it looks a lot like how I did it. :)
The shoreline works as a good leading line, the dark water vs the shore provides good contrast. Only the brightness of the area under the bridge is strange, it looks like a different B&W editing. Not bad at all becasue it provides a clear point of focus for the viewer. I like it how that works out.
Wow. How did you get the sky so dark above the bridge and the view through the bridge so bright? Very dramatic. I do feel, however that a large portion of the foreground is redundant and that cropping away about a third of the frame from the bottom might add a little more impact.
really good motif, maybe it would have been better just as it was shot or in plain b/w, and by the way, maybe a bit closer framing would have been nicer on my opinion
