The week Missed

Well I didn't actually miss last week's class, I just wasn't feeling well. So I don't have any feed back on what happened. I've been looking at these demo reels and so far I've only found one that I like for editors. I'm wondering what medium(s) we're allowed to use? Only real-life imagery or are we allowed to use some cartoons? Oh well, I'll find out when I get to class next.
