Paint/Video Effects

When researching effects for my music video, I wanted to try out more techniques using the green screen, but with using a person and changing the background. Taking a piece of paper, I filmed myself painting and flicking green paper on the paper. I then scanned the footage onto the computer and put the footage into Adobe After Effects. Taking footage I had used in earlier projects, I as able to key in the film where the green paint had been splattered on the paper, so it looked like I was 'ficking' the footage onto the paper with a paintbrush, which overall looked very effective. I also liked the idea because it differed from a lot of music videos, and I couldn't find any one who had used a similiar idea.
