This is not a tutorial. It is a sheet of generic chibi anime faces. Please for god sakes, if you're making a "tutorial" first get some sort of basic understanding of human facial structure. Our faces are not circles. our mouths never look like P, U, X or 3 and certainly never look like a square or triangle, oh and they also can not leave the bottom jaw. The mouths on the fourth row are simply unrealistic. Eyes can not be an X or spirals or have one bigger than the other. If you were to ever use any of these in a serious, non kawaii desu drawing they would ruin the entire thing. Pretty please with a onigiri-neko on top, learn anatomy , take two aspirins and call me in the morning.
