It appears to me that the bubble acts almost as a magnifing glass and the rest of the photo is out of focus as it should be due to the closenes of the subject to the camera lens. Nice effect, I like the overall look.
We don’t make art to show someone what something looks like. All this requires is eyes (or a lens). Art is supposed to have meaning, emotion, power, or magic. Alan & Mario "FourThirds"
