The rough look of the chalk and charcoal brush is SO GOOD for Chu Shuzhi here! I love ALL the different ways you've drawn him but this kinda rough look works really well for him. (Unless Changcheng turns up, in which case he will be look soft and tender when he imagines no one's looking.) I also like how introspective he looks here! Like he's thinking about something very serious.

The birb!!! It looks so real, like it's about to fly off the page!!! *clapping*
