i tried to draw this girl, her real face is square shaped but she still looks feminine, but whenever i try to draw her to square shape makes it look like a boy's face, any tips?

also i want to ask, i used to draw anime as a kid and stopped, now i want to get back into it seriously and hopefully get good enough to write my own manga, but i want to learn anatomy.

you guys think it's better to study from some book or course or should i just keep drawing by using models like this and do it until i get better?

sorry if it's a dumb question, i hope everyone is doing well
