I absolutely love the mood and feel here - some REALLY great "atmosphere", however I do have a few nitpicks. I have to agree with Light Guru in that I'd probably straighten the shot a tad and I do find the soft focus on the front of the bridge (lower right corner) to be a bit distracting...not sure what/how you shot this, but I'd be tempted to try a smaller aperture and/or a tripod for a bit more DOF there. Normally I don't mind a shallow DOF at all, however in this case it really feels like things could be a bit sharper. Also...and this is probably a bit more subjective, but I think I might have tried a slightly different angle (or two) with this shot. As the viewer...trying to imagine this scene as you were looking at it thru the viewfinder...I think I would have tried moving to the left a bit (if possible) to bring the bridge across/thru the image a bit more. It's a very interesting scene, but I think I would have tried to let the bridge dominate a fair bit more of of the composition.
Just my own opinion...again, lovely mood with that shot.
