I agree with the premise. Just because a woman, or man for that matter, looks pleasingly at her reflection is a mirror, does not necessarily imply narcissism. It can be taken as a pure joy in having presented oneself beautifully to the world, and thus why shouldn't one also gain delight in one's achievement? In that last picture, her lover also want her to share in the beauty she has offered him.
But it is walking a dangerous edge. Like anything inherently addictive, we need to remain on guard against slipping into the entrapment of the ego on both sides: self-pleasure and self-pity.
