failed tutorial
altough paved with good intentions your tutorial is not precise and tries to teach people a easy way to make things. WIch reduces the quality and makes some movie stuff look like an error.
Making movie clips of mouths is an error because the lips are not precise at what the character say. you wouldnt like your character witha mouth wide open when he is pronouncing a U or aN O. you get me?
still I guess works with newcomers to flash.
