This part Sunday, on my weekly drawing workshop (free and online) we learned to draw simple cartoon expressions and how to apply them to a character. I just uploaded a new video on this topic on my youtube channel SKETCHMAN DRAWS, please consider subscribing. I make at least two videos per week.
Here is the link to my meetup group, if you become a member you can get notification on when I organize my next events: https://www.meetup.com/Bangkok-Geeks-Meetup/
