While I love her eyes and find the color of her hair lovely, I don't "feel" the pink of her lipstick works well with the hair and eyes. OTOH, I don't think it converted well into b/w - the formerly pink lips are tad too pale, almost lost against her skin. So...
I'd consider PSing the lips into another shade, then probably go with the color to keep those wonderful eyes.
But then again, what do I know?
