How does understanding human anatomy help with drawing portraits?
I’ve been interested in drawing lately, especially portraits. I talked to a mentor for some advice and she said that the understanding of basic human anatomy can help when recreating the look of a person because you can use tricks to break a few rules and make things look more dynamic or prettier.
I was wondering, how does that exactly help and what rules are there to break to make the drawing look more interesting? Also, what parts are there of anatomy that you can study to help with drawing?
I really want to learn a lot so if you can then please include extra information ^_^
