The four aces of love

These are four characters i designed a while ago for a comic that unfortunately never was.
They represent four stages of love:

Clubs is a little girl, she represents the crush: pure, funny and a little silly.
Hearts is a young, androgynous man and represents passion: sensual and a bit sex-obsessed.
Diamonds is a violent, muscular man and he's the jealousy, the rage: he's obsessive over what is his or perceives as his.
Spades is a sad young woman and represents pain an lost love: he's always sad over things that she never even did.
