Character - Initial Designs

After looking at some Team Fortress 2 styled characters I begun to think which character or even class character I would like. My initial thoughts were to stick with simple ideas like a tall and skinny character or a short and fat characters. However the problem with this is that both these characters have already been donein the form of the Sniper and the Heavy.

So instead I think I will create a hybrid class and try to find a niche in the Team Fortress so that my character may fulfill a role.
