Learn the most important core concept of drawing-Values. Start with just black & white Notan, then add a middle value for three values (class 1), learn to create the illusion of realism with 5 values and what they mean in Light Logic (class 2), and train your eyes to capture 9 values from dark to light and make a value scale that you use for your drawings now and in the future (3rd class).
