Shoes Contour Line drawing

Create a contour line drawing of a pile of shoes. Use detailed contour lines and NOT sketchy lines. The drawing will fill a 12"x18" paper in landscape orientation. The shoes should be drawn large enough so the drawing stretches across the whole paper, touching the left and right edges.

INKING
After completing the drawing, use a black fine point marker to trace over all your lines. Each line should use LINE VARIATION to create interest and depth. Every line should show variation, meaning a transition from thick to thin.
