Mmmm... that's geeky!
This is exactly the type of geekiness I most enjoy (and probably that I myself often display about my passions of choice). This guy draws, draws well, and is very knowledgeable about his tools and tips to work and maintain those tools. From auto mechanics to graphic artists, I really can appreciate this level of competence and joy in one's work.
