From their blog:
In today’s Insider, I’d like to take a minute to share with you how my process for drawing concept art has changed over the years. In the past, I was a pure pencil artist. Only the feeling of graphite scratching on paper would give me the inspiration to design. Once a drawing was finished, I scanned it into the computer and then sent it off for feedback. If anything needed to be revised, the mechanical pencil came out and the process started all over again. That process produces A LOT of paper, as the boxes of drawings I have can attest.
About a year ago, I set out to break free of my paper fortress and learn to draw entirely digitally. I was already doing a lot of digital painting, but the discipline of drawing is very different from painting. Drawing calls for very precise line work and line weight. I wasn’t sure I could create line work with the same precision digitally that I could with a physical medium. But I was determined to give it a try.
Eventually, the sounds of scribbling on paper gave way to the tap-tap of stylus to drawing tablet. I had to train my eyes to look at the screen and not at the pen tip. It took a little getting used to, but once I got the hang of it, I was sold. Revisions are now a snap! Repetitive details a cakewalk! My speed has increased two fold at least.
So, say goodbye to the drawings of the past, And say hello to the drawings of the future.
