Request for some basic concepts

My friend is starting some roleplaying thing. He and I both thought it would be cool if people who join could design there own character. It would be highly appreciated if someone could draw basic concepts of the classes you can be (the classes can be found at http://www.geocities.com/dragonthelast//club.html)

Remeber, they in no way have to be detailed. That can be added on by people who are joining.

Thanks in advance.
