An artist senpai once pointed out that no one ever naturally does the eyebrow thing Felix does in his last panel (I'm not numbering them because the paneling's too bad) and it's relied on too much in cartooning and ever since reading that I haven't used that expression, so please enjoy this rare occurrence.
Not that you should listen to every bit of art advice you see, but I think it's made me a better artist, so I have no regrets.
