Those are actually quite good

. You've got the facial expressions matched very well with the emotions you wrote next to the characters. Ducky's "mischief" one also makes her look either annoyed or angry but she just won't let it out

I gotta admit, with no offense intended whatsoever, that Cera's expression is not only the most dramatic but it even almost made me start crying. Because she very seldom cries makes it more shocking, and in this drawing she looks like she's devastated about something. Her letting that kind of emotion show is a bit disturbing, but at the same time a fresh difference from her normally tough, internalizer self.
