Green Screen Editing Test #1

This is my first editing test using the green screen filter.

I put the clip into After Effects and began adjust the colour key in order to remove the green from the shot. However, due to lighting mistakes, this did not go very well. The colour has removed half of my subject (Richard) and makes him look very cartoon-like. Also, due to the green reflection on his face (another lighting mistake), the colour of his face has dramatically tinted yellow, adding to the cartoon-look feel - a look I was not going for.

I have other test  footage from this shoot that I have experimented with.
