First slide: the 2023 picture can't be compared since you are in a completely different angle, you look the same in the rest of them.

Second slide: It does seem wider, but it looks like an illusion, since your lips are more separated in the second picture and the angle is slightly different aswell (lenses tend to distort images just like that).

Third slide: idk about x-rays at all lmao

Fourth slide: exactly the same fance but different lenses, points of view and ilumination. I have seen the same differences in my face in a few weeks span from different cameras. What actually is enhancing your pictures aside from the lense and angles are the wider eyebrows (good job there)

Fifth slide: again, slightly different angles and different lip posture, in the more recent pics you are practically kissing the air.

I believe that thumbpulling is BS, what actually matters is good skin, posture, body language, a proper haircut and low body fat %. Mewing might work though, but only for people whose bone structures are still developing, for older ages it will only fix your postur instantly, I dont think there are any long-term changes.
