I like the concept of it and the whole thing goes pretty well- the only thing that's a bit niggly is the transparency of the girl. It makes the character harder to focus on. One solution is perhaps hitting control L and changing the lighting, or using the lighting effects render. That way you can darknen the scan and still keep it up at 100% opacity or transparency or whatever it's called. Extraction is pretty good though the hair still has a few (unnoticeable) bumps- because of the dark nature of the wall you could have also thought about colour burning the edges to also help the scan blend into the darkness.
Great concept, good work :D Kudos for you!
