In my opinion, an true artist is someone without limits. I mean, not a drawer, a musician, or a writer, no an artist is the creator of an atmospher, he might use writing, drawing, music, but also every of these technics.
About the digital, for me it is a tool, and don't influe on the true skills. It is for people, like me, who are obsessed by the result and don't care the technics used or anything. And usually, someone who draws great things one computer have also serious paper skills...
