Pingpang ball design

it is the hardest work i have ever seen. how can a people finish 40 balls in 5 days? if so, he/ she should be superman! however, we are all superman/superwoman, because we have all done!

the assignment is design 40 pingpang balls with 4 different kinds of emotion ( happy, angry, surprise, etc). i chose "happy","surprise","sad" and "nervious". haha, i'm not sure whether you can find these emotions in my design.

show time!
