Hm...how about colouring in the mouth. Make the teeth white, have the stuff surrounding the green deepish pink with purple stripes much like Cheshire. For the quote, how bout making it black but white at the edge. And for the background making it gradient from blue to red or have red hearts and cards at one end and a blue ribbon and black and white stripe pattern at the other.
