What do you look for in a rigging demo reel?

Hope this helps a lot of people. What should students have in their rigging demo reel and how could they stand out?

I ask this question because I watch a bunch of demo reels to get an idea of what to put in and what to learn, but I always see similar things emphasized. Some things someone said on another thread: IK/FK switch, match and stretch, some dynamic rigging, MEL, and the obvious, a wide range of rigs, to name a few.

there are plenty of posts on this forum that I believe will answer your question.
