I don't know why, but most of the time, I make my OCs rather plain-looking and not over-the-top.  I'm not gonna go for that white-haired violet-eyed lady in that awesome armor and great breasts, I'm just gonna go for your average looking brown-haired woman with plain clothes and not-so-great breasts.  I don't know, I guess I just prefer playing Average Joe characters and slowly develop them into being not so average.
