Meaning
Big, tall eyes and a wide open mouth give this face an eager, wide-awake kind of happiness. It reads as excited and enthusiastic rather than amused, the face of someone who just heard a plan they love.
It suits replies to invitations, announcements and anything you are looking forward to: “Road trip this weekend? Yes please 😃” Compared with the plain grinning face it feels a touch more childlike and energetic, which makes it great for family chats and friendly customer messages, but a bit much for serious news.
