I've been looking for a simple expression guide for a while. I actually checked quite a few drawing books but couldn't find what I was looking for. Specifically since I came to Japan I noticed they seem to have a very set way to draw simple happy face style expressions and I wanted a couple of pages with examples. My guess is that Japanese kids are all taught from the same books in school so a lot of them end up drawing the same types of simple characters. I don't mean to suggest the Japanese are not creative, only that many of them must have studied the same happy faces since they are so common
Anyway, I never did find a Japanese book with a list of the different faces but then I found the Ed Emberley books and he had a great page with lots of very simple faces. Looking at it it was pretty clear there was pattern, 3 types of eyes, 4 mouths, 3 eyebrows and every combination of those make quite a few expressions.
Here's my interpretation so now I have my reference.
Of course that's not every possible face but it's surprising how many expressions those 10 parts cover. Here's a few they don't.
Apply your own interpretations of what they each express but please be nice 
Now if someone could point me to a stick figure action pose guide!
They remind me of the Natchan juice caps, but I think there are only four different caps. They really should expand the range of emoticons on the caps, though.
Some of my students say that if you buy Natchan in the morning, the cap you get will determine what sort of day you’re going to have (happy, sad, mischievous or upset). Surely there are more than 4 kinds of day a person can have?
Gman you’ve gone locoroco … looks excellent fun, wish I was there to download the demo.
