Last night, students made drawings addressing proportions. The approach was to identify the basic forms within the more complex object. In other words, start by drawing the cylinders, cones, spheres, etc. Notice in Elliot's drawing above the placement of ellipses as the structure changes from concave to convex. In addition, you can see the faint lines of the rectangular shape before addressing the curvilinear contours. Remember, it helps to see curves when compared to a straight line or edge.
