Class three is about sketch people's faces in oilpastel which is kind of material between crayon and chalk. At first, we have to use the black pastel to make the contour, and draw the shadow parts of on the face. Then, add use the white one to make the other part. The teacher kept reminding us not to focus on the detail but the whole shap of face. For me, the most difficult position is lip since there are some crease on it so I have revised it for times. Besides, fingers were also challenge for me! In the end, the face seemed more solid after putting the towel on it. Even though it was not equil to the original picture in perfect, I still feel satisfied with it! :D
