Tip...If you draw always without tracing from a photo you develop your amazing artists eyes that will give you the measurements and the details without using any tools other than from your living subjects and models. Only a skilled draughtsman artist understands the photographic distortions. So when you trace lines of the details from photos many students do not know how to see these angles, colours and values giving you false information.
