Hunter eyes are impossible to achieve without surgery or genetics, whoever says otherwise is coping. Not even eyelid pulling or squintmaxxing btw.
Face structure is nearly impossible to change without dental treatment, mewing and plastic surgery. Depends on what you're trying to achieve and what you already have, your age and your dental issues etc.
Cheekbones, again, nearly impossible to change without dental treatment, mewing and plastic surgery.
Jawline, this depends on if you have good jaw development or not, if you are heavily recessed and have no chin, then you obviously aren't gonna get a jawline by losing weight like a different person who already has a good jaw development and chin hiding underneath fat.
Buccal fat, sugery or lose weight/aging.
I can give you better advice if you be more specific on what you are trying to achieve, and what you already have
