X-Factor portraits

I'm getting to hang my three recent LJ portraits at the upcoming Midsummer Night's Dream party held by the Vampyre Connexion.
Its an enjoyable challenge to paint interesting, charismatic individuals as I am equally interested in showing something of the personality as well as their striking physical appearance.
However, conventional good-looks or youth have absolutely nothing to do with the subjects I choose.

I suppose you could say that they must have the X-Factor.
