I always urged my contemporaries to look for interest and inspiration to the development and study of drawing, but they would not listen. They thought the road to salvation lay by the way of colour.
What is certain is that setting a piece of nature in place and drawing it are two very different things.
Drawing is your understanding of form.
Drawing is not the same as form, it is a way of seeing form.
Make a drawing. Start it all over again, trace it. Start it and trace it again.
