I think it’s important to keep up with “traditional” methods of illustration. Well, not going so far as cave-painting or woodcuts, but i have done linoleum cuts! These days, though, we’re too enamored of digital media. It’s very useful, and fun to do, and creates unique artwork – but when the massive solar flare knocks out ALL electronics – what will you do?! So, you see, using pencils is actually ahead of its’ time! Just don’t let “Planet of the Apes” see you drawing when they take over!
