The first one has some potential. I don't think the angle you went for really works. It could have been a lot more interesting if you got the camera lower, and had your model pose exactly in the middle of the bridge. Being off to camera right bothers me a bit. The pose also leaves something to be desired.
# 2 I just don't get. I see the graffiti and there's a gas mask and a guy in a tie. Nothing really comes together especially since the model isn't engaging the camera in anyway.
I can see you were going for something different with the gas mask and tie. I think in a different environment it could have had more of an impact. Maybe the model doing something normal in this attire would gain more interest. Sitting at a bistro having a cup of coffee. Bring the framing in close to catch some details off the mask etc... Not sure if any of that would work I'm just throwing ideas out there.
