I wouldn't make the cheeks puff out more, I'd pull the lips in a little bit... and make the eyes a bit more "angry". Kids who hold their breath and pout often are throwing a temper tantrum, and are angry for one reason or another. But pretty darn good otherwise, Ron. And am I the only one that noticed the texture problem on the side of the tongue in the tongue poses?

Remember, kids! Napalm is Nature's Toothpaste!
