Here's another really quick sketch I did for this week's Illustration Friday, topic - Lesson:
Mama Bird's trying to figure out just what the little one is doing wrong. What I learned from drawing her is that it's a bit tricky to convey the expression of 'thoughtful criticism' on a bird when you have only one eye with which to portray the expression. Cocking the head helps, but it's still tricky. And I think I almost got it, but my mind's eye-version is a still a whole lot better.
