Of course, the beauty mask idea only works with a ';westernised'; version of the definition of beauty despite being grounded in the theory of the golden mean.
beauty is a different concept for each singular person, but if you want to know about the rules of beauty in painting you have to refere at the studies of old masters like L. Da Vinci, michelangelo, Rafaele Santi etc... they have done many studies about body and face harmony, you have also the measurements of a body or face...


but i will advice you to follow your eyes and trust them...
Do the 1 to 10 method. 1 being the ugliest 10 being the prettiest.
Beauty Coefficient is equal to the state of your mind.
chin=cheek bone squared minus length of nose divided by the root of the eye color
