The two night shots don't have convincing blacks, they don't quite sell is "night" photographs. They're not super interesting, but they're not bad. Particularly the last one, if you got rid of that "veiled" look by pushing the shadows down to black if would be quite nice. I never really like the look of modern cars in these things for some reason, but whatcha gonna do?
The first one is just a kind of an unattractive building on a road. I can see that you tried to find something there with the angle of view, and you get an A for effort, I just don't think it worked very well.
