This one, is pretty simple. Like the traits, you have too keep it balanced, make it complex enough so that it doesn't look/sound boring to the viewer, but make sure that it's not so detailed that you don't even know what it is anymore.

It's just not scary and really overused. It concludes of: Torn clothing A knife (It Looks like you made a jam sandwich XD(it's an overused weapon)) Emo hair
