I like #2 the best. A very simple subject, not that busy of a picture, but i get this sort of eerie feel when looking at that one. If the camera would've been a little closer to the ground in #2, it would've looked better in my opinion.
there doesn't seem to be much to the photos, #2 has the most interest. Try getting higher or lower than eye level and trying different angles to give the photos a bit more interest
