Robert Liberace is a contemporary artist who also uses hatching in his drawings and paintings. He is a master of drawing and an expert on anatomy. First, lets take a look at this 4 minute video on YouTube which will show what pages of text could not adequately explain. Yes, he draws at the speed shown. Obviously the image is in his mind in extreme detail and his hand just tries to keep up. His sketches in oils follow a similar technique of hatching, cross hatching and scrubbing the brush as he does with a pencil or charcoal.
He also does sculpture and very finely finished paintings. The following 4.5 minute video gives an example of his latitude of materials. The pen and ink with wash sketch at the end is delightful.
