For twilight samurai's "Express Yourself!" challenge. Expressions are my favorite thing to draw. In fact, the first thing I do when I come up with a new story and characters is draw something like this to flesh out the characters.
I'm leaving this one in black & white because I could never ink this delicately enough. To get some of these expressions, I had scenes from the story in mind. (For instance, the "upset" one. For the reason he's like this, look here.)
Hope you like it!
