I am actually quite intrigued and captured by the first image. Ooh, I do like it, just about the way it is!
It is interesting to have a bridge at night. It is interesting to have a low camera-angle, perhaps in the pool of light from those lamps. If those lamps now each sprayed out a pool of light … not enough light, oh no, this is a strangely dismal-feeling bridge at 2:30 in the morning, to be so busy with a rush of traffic at dawn…
I am intrigued by the fact that this image is monochrome. What if you keep it monochrome? I like the fact that it is grainy; rough; unrefined.
What if you didn’t fill it with mist, but let the end of the light itself do the trick? What if there was nothing at the end of the bridge? If it just fades to black and that is it?
You can do several treatments of this model; you know that of course. So… what if in this particular treatment of the scene you decided that you are already very, very close to something that feels really, really, cool and different (to me)? 
Enjoy!
