I like 1, 2 & 3 # 1 being my favorite. Did you do this (#1) using a long exposure and a zoom lens (zooming in/out during exposure?).
Definately an eye catcher.
The first two are double exposures, in-camera. You need a tripod foir this kind of photography and a multiple feature on your camera.
1) The first image is taken out of focus and the second is taken over the first, zoomed at about 1/2 second.
2) second iimage s taken, one in focus, the second over the first and slightly out of focus with shallow depth of field. This is known as the Orton technique. A variation, is to simply take the same two photos separately at half the exposure value and combine and overlap later in photoshop.
3) the third is simply a vertical pan at about 1/8 of second. Many consider this "overdone." I say, if the subject moves you, take it as it suits you, straight, motion, zoom, pan, whatever.
One final piece of advice, no amount of special techniques or experimentation can take the place of solid compositions that have interesting subject matter and that expresses something.
