I love the sepia tones here. It give it a feel of an old photograph despite the cartoony style. And you've populated the picture so thickly. This is a case where business is an asset. There are so many people to look at and details to take in that it becomes a nice puzzle to linger over. What, for example, I wonder is the story of the boy staring right at the audience in the lower right? The lady in the hat is fantastically designed, and the little girl who makes the center of the piece with the flower in her hair is marvelous. I'm assuming (sorry, I'm not familiar with your works ) that she's the younger Yersu?
