Projected Background Portrait

There is a portrait technique where the photographer projects a slide or a video on the background, of images previously taken of the same subject in other poses. I think it is very cool concept and I have seen some fantastic images done that way. I will try it myself once I can get a projector.
For now though, I have created a similar concept using two images which I blended in photoshop. It is not the same thing but I like the way it turned out.
Feel free to comment on the image and, if you know the technique I described above, and you have any  samples of it, you can post a link to them.

Cheers...
