Marcello Barenghi is an amazing artist who works in a combination of mediums, including pen, pencil, marker, and airbrushing. He achieves some impressive depth, through the use of reflection, and dynamic lighting. He recently posted a series that shows him drawing photo-realistic version of the most popular Star Wars characters. He captured the drawing process for each image using time-lapse, so we can see the images come together in just minutes. Obviously, the actual drawings took much, much longer.
