Chuan-Bin Chung of Shu-Te University in Taiwan makes it look so easy. He quickly sketches out detailed drawings of the human from, from the skeleton all the way up to the muscles. It reflects how he teaches students to accurately depict the body. He tells Bored Panda:
Yes, we have a textbook. But we don’t read it, we draw it. Students, majoring in this area, cannot learn by just reading the pictures on books. Instead, we learn while drawing something. In my classes, students have to draw what I am demonstrating on the chalkboard.
Practice has made him perfect at his craft. Chung uses a straight edge, but otherwise creates these colorful and precise chalk drawings by hand. You can see more screenshots from his YouTube channel at Bored Panda.
