My oldest daughter is an Art teacher at a local charter school. For years she has run the after school art program as a volunteer. When the Jr. High needed to hire an art teacher, they asked her first. This semester, she had them do self portraits and asked if I would come in and help. We talked about proportion, basic facial placement of features. Then we discussed value and the importance of drawing what you see, not what you think you see. I taught them to turn their pictures upside down to check for mistakes and think in terms of shapes working large to small. Talked too about the angle of the line, it's placement on the surface and it's length. All in all, it was fun and I hope informative for the kids. Here are the two portraits I ended up doing in class.
Colin Morgan has such an interesting face.
