I noticed that I don't pay enough attention to the form of the object I am drawing. I care more about the contour and that's a no-no. Makes my stuff look flat.
I think this exercice will help me fix that. After drawing a rough study of the figure, I go over every surface and try to identify it's direction in space. It really makes you think about the shape of what you're drawing.
Also it was hella fun. Wool boobies.
