Is that military or civillian? Where is there a bridge top in the picture 9if that's what it is)? It needs more purpose and to be more in focus. Otherwise the idea has potential.
Fits the challenge quite well, but seems out of focus. I notice that you can see some of the lines are pixellated - perhaps you can try a higher resolution shot. Composition is nice, and I love the lighting.
This is minimalist in the classic sense more than in the only-small-portion sense, but I'm not docking points for that. Unfortunately, the eye is drawn to the light at the top, which seems blurry, and I do dock points for that. The image is also somewhat drab. Boosting contrast might have helped.
