I have the same issue- dead eyes, fake looking smile, insincere appearance, unnatural. Unless....my photo is taken by a close friend. then, those dead eyes and the rest disappear. If a stranger takes my photo, forget it. It's about the "energy" you feel when your photo is being taken. If you're sincerely happy about the person who's behind the camera, if they know you well, I'd bet your image looks 100% better. This is true for me at least.
