When Butthead tells Beavis that "You can't polish a turd," What he means is that great drawing is the indispensable foundation to any great work of art. Before struggling with paint, art students need to focus on building strong drawing skills. Learn to see spatial relationships, points, tilts, shapes, and translate them to paper. Learn to model form based on the relationship of the light source to your subject . . . etc. Be relentless in your pursuit to acheive great drawing skill.
