Make it a habit to visit Jeff's Academy site. One of the posts mentions the Movie Screenshot gallery blog, which looks to become a fantastic resource. Go through the posts and study the framing of the actors or the general composition of the shots. Think about how you can make your own shots more interesting, how you can use specific staging to advance the story point in your clip.
I also recommend the DVD "Visions of Light" as well as the following books (click here).
