Well, here goes:
All seem to be technically OK: focus is fine, exposure is fine.
Nr. 1: Subject is pretty much dead-center and there is no face on the supposedly pretty girl. Move your subject off center.
Nr. 2: Best of bunch in some ways, but seems pointless. Maybe the large dark areas are a problem Not every scene that the eye likes can be put into a photograph. Still, I could live with this thing on my wall; I might never love it, but it would be pleasant.
Nr. 3: Too many competing elements by the time one has the pole, the guy wires, and all of the clouds.
Even with that, many people have done a lot worse. Just keep trying, you'll get there.
