The thing about kissy-face pose is that it's one of the few expressions that you DON'T really want to exaggerate. Practice with your lips in the mirror - too exaggerated of a pucker will look weird and unflattering.
Yeah I practiced a bit, and it doesn't look horrible, but it's something I can easily pass on even if that's her character so it's not really needed.
I usually assume kissy face is usually something that's not flattering in costume or not.
