YES! I'm no storyboard artist (although that'd be an awesome job) but whenever I draw comics or cartoons, I would continually catch myself making the faces my characters would! Btw, are you drawing on a Surface Pro 3 in this comic?
I do this when I'm writing but I never see the light of day so nobody ever watches me do it. I think I do this when I'm drawing humans ??? But I take so long to draw human portraits that I feel like my entire body goes numb before anyone can catch a glimpse of what ever expression I'm making. (wooden chairs are the best.)
