Mid-day sun does nothing for these pictures. Try in the morning or at night. The angles of them seem like from a humans perspective - way too boring. Getting lower to the ground (even just a bit, the camera doesn't have to be on the ground) makes anything much more interesting.
#2 the blur on the left is distracting. It also looks like it has a bit of motion blur.
#3 is a piece of metal in a pond. Not very interesting. The colours are pretty boring, and it is dead center (albeit at an angle, which is good).
