Very cool. You might try shifting the "clear" area up a tad, but otherwise it transforms this pic into something really cool.
The base image itself is interesting. Where is that? Looks like a cool place to hang out on a summer's eve.
I tried this technique with an image of my Z4 in my driveway. It worked pretty well, although I was a newb at PS at the time. I should go back and try it again.
