(The content of the course is full of dry goods, and the focus of some skulls is covered, from the beginning of the skull to the muscles and then to the facial expression depiction. For example, when I started sketching, I felt strange because I didn't watch the head class, but I didn't know where it was? After learning the head lesson, I know the reason. The bone positions of some important parts of the head are not found correctly, and then it will be much better in an instant after following the tutorial!)
