@superbaby In my opinion, Font A is good for the shouting bubbles, but you might wish to use a different one for the last, plain speech bubble, "Director!".
Not really a fan of Fonts B and C.
P.S.: Also, I'm not sure MDex moderators will think kindly of making a release to test fonts. I don't mind, but some readers might. You could use the forums in this site for that.
