The female main character’s pose, her reaction, in the last panel is quite wrong. It was what I had, so I ran with it, but it’s not right. Of course, I don’t know how one SHOULD respond to a lobster taking a baseball bat to someone’s knees. So, maybe it’s not so wrong after all?
I had a little fun with the third panel, breaking the border with the bat but nothing else and throwing in a “crack!” in a widened gutter. I like it: it gives visual heft to the bat as a key item and the crack, being in the gutter with the same slope as the bat, connects the bat to the action and anchors that action between panels 3 and 4. It sets up the timeline, connecting the two events and identifying the agent of action. Perhaps I put too much behind it, but I like the results.
