Somebody may think that by drawing the mouth by a single line it's done, but that would be a big error. The mouth is the major expression indicator. I'll get right to the thing.
The expressios are :smile, neutral, laugh, shout(angry), shout(happy), super smile etc. Here we've got a picture of some we'll learn in the novice section.The first mouth means surprise or interrest(you could have seen its use in the novice section-drawing eyes.
The second is a smile from the front view.
The third is an angry mouth also from front view.
The fourth is a smile from 3/4 view.
The fifth is a neutral expression.
The rest of the mouths are all from 3/4 view.
The typical supersmile.
A loud laugh(in order to make it look like the mouth is open you can see the tongue-represented by a line)
The last is a loud and angry shout. The difference between the laugh and shout is that the bottom of the mouth is wider than the top when you want to get a shout and vice versa.
