I am not sure about the floating bit, but I really like the phtoograph. The contrast between the guy and the girls and the gaze of the first one to him. Good street photography, well stolen in good timing :)
They very much do appear to be floating by, which in a still is pretty clever!
The two of them are completely out of place. Everything else is just an ordinary every day street scene but those two just look like they have been pulled from a completely different scene and placed right there on the street unexpectedly.
I really like this one, it's interesting how oblivious the people are to one another and there is also a lot of contrast between the two women and the construction worker. The depth of field works well to direct the attention and make the photo not too busy.
Sort of looks set up even though I know for sure it's not. You know, pose good looking guy and photograph the female reaction. (Or male come to that) Well spotted
