In order to let the students experience the effect of the class more intuitively, Tina has opened a free open class for everyone (the open class is the video tutorial part, not including the comment class). This video includes a detailed introduction to the materials needed for color pencil drawing, as well as a full video tutorial. The subject matter of this open class is not deliberately divided into the content of the class of the master class or the class of cute goods, the purpose is to let everyone experience the class process and the level of detail of the lecture.
