In assignment this week we don't animate yet, but also discovered the importance of pose. Whether or not an animation is a set of extreme poses and their intermediary! Dan Graham called extreme poses as "a story-telling drawing". An animator must certainly be sensitive to poses and gestures that portray the various moods and emotions that story telling demands. 

It's also good to know about line of action. 
As described in the book by Preston Blair "The line of Action is the basis for simplicity rhythm, and in animation directness. Start your animation with a line of action. Then draw the Skeleton and the details."

Anyway ... Here is my assignment for week 2.
