Lots of people are going to reply to this and tell you it looks cool. Because people seem to compliment everything on here.

I tell it like it is.

It's not cool. It's kinda crappy. The perspectives are all off and look a bit silly.

BUT ...

I do see the direction you are going with it, and I think the concept is freakin' awesome and has a LOT of potential. I really think the idea is neat as hell.

... In fact, it's such an interesting and cool concept, I might steal it. Thanks for the inspiration.

I kinda have to agree with Eric but I'm nicer - LOL! To me, the photoshop filter effect is what kills it. It makes me think that your chromakey extractions were not that clean and you used a filter to hide it.

If you look at the images, you will see that each are "lit" differently and the tones and contrasts doesn't match from person to person - that is important (to me) for good chromakey. In the image below, the hardest part was getting model's image to match the look and tones of the rest of the image. The other thing I was conscious of was that the model is 5" 11" so I had to depict her as very tall, taller than most people in the image.  While it's not perfect to me, I am using it to illustrate a point. Don't get me wrong, for your first greenscreen, it is very, very good and very cool concept



To get her to match the rest of the photo, I would have to blur her a bit more and boost the contrast. I decided not to because I wanted the focus to be on her. However, I feel that was a mistake and I should blur her to match - I don't think she would have any problem standing out.

I am dabbling with green-screen as well. I think it is a great experimental technique. To the original  poster, since you asked, I thing this is a great first result. But I also agree with the others that light consistance would help and try to avoid the Photoshop filter look. There are several tools out there for doing this kind of thing. Some are even free. Right Hemisphere recently released its DeepPaint software free for download. Not as pworful as Painter, say, but it has some good features. What I am talking about here is not the greenscreen extraction, but the "photo to oil painting" look, which I have also dabbled with separately and in combination with green screen.

Keep at it, you are off to a good start.
