This is how i implimented a background in after effects. I only used two lights so there are some dodgy shadows and for speed i just used a photograph in this test but it showed that this method worked fine. I also added an animated flower i created in maya just to see what effect a moving background would have on the camera movement but it worked well so i will continue with the green screen idea and begin designing an enviroment based on previous paintings and maya enviroments and storyline that can incorporate stop motion, 3d and 2d animation.
