Body language

As a board artist, you want to be able to communicate what the character is feeling. A lot of times it's the opposite of what he is saying. you can use body language to show this. For example watch the way people point their feet. If you walk up to two people and they point their feet towards you, they want you to join their group. If not, they want you to leave. A person will usually point their foot off in the direction they want to go in as well. Watch people talking. If one person is late for a meeting, he will point his foot off in that direction. Here is a good book on the subject: "What Every Body is saying." by Joe Navarro
