5th graders drew self portraits of themselves in winter weather gear. They loved this portrait project because it was a cropped portrait and they didn't have to draw their faces! We discussed proper proportion when drawing bodies. So they needed to pay attention to how big their hands were, how wide their shoulders were, the size of their neck, and the width of the rest of their body. They did a great job with all the details!
