I believe that to succeed with digital media, you still need to apply basic visualization and rendering skills. Using digital media doesn't mean you don't have to draw like a classic master, but drawing skills are a distinct advantage. The real advantage of digital media is in the freedom of experimentation. With a digital file, if you get a spontaneous idea for an alteration, you can give it a try. If after a few minutes or a few hours, you don't like the direction you're going in, and if you've saved the original file, you can throw your experiment away.
Nothing is lost but a few hours.
You can't do that with traditional media. If you spend four hours repainting a passage and then decide you don't like it, there's no going back. Though the digital realm offers some wonderful advantages, there are still limitations. Even though you can attain the illusion of a painterly look with digital media, much of what we find appealing about traditional media comes from the real tactile sense you can only get with paint on canvas, or charcoal on paper. Much of what we find compelling about art is based on the wonderful unpredictability of the artist's interaction with the art medium.
