Motion graphics

Well hello there and yea… I have a rather vague question for you guys. But bear with me as I do not have any one particular bent of mind myself.

Basically, I’m planning to start with some motion graphics projects in a few days and I wish to compile them for a demoreel. And this demoreel, of course, is something I wish to show if I apply for a job.

So keeping that thing in mind, I wanted to ask you guys, what would be some styles/stuff that should be treated as staple to such reels and what all should I take care of.

As I said, I realize that this is a pretty vague question, but I’m only trying to figure out a general view on things from people who are experienced in the field. So anything you say could and probably will, be much help.

Thanks.
