CGArena has posted 'Pigeon Impossible Podcasts - Part 1' describing the general outline of how Lucas Martell worked on his film. He's a humorous guy and his videos are fun to watch. The podcast on 'Multipass Compositing' explains the compositing workflow he employed in his film, which is a great overview on the topic of compositing.
Here are some of the links to artists interested in making good compositing:

For 3D Compositing Guide by Simon Reeves, you can access both part 1 & part 2.
