Emotional Sack

I've finished my emotional flour sack exercise for animation 1. Here's the situation: The sack enters and notices someone he knows in the audience. It turns out it's this girl he secretly likes. He waves to try to get her attention, but she doesn't see him. He waves more violently and she turns around mid-wave. He's like o.O and freezes in fear. The sack becomes very shy/uncomfortable, and makes a quick exit.

Requirements: Show at least two emotions with the flour sack without the use of props or layouts.

I'm semi-happy with it. I looked at it a few seconds ago and thought that he holds for a tad too long in the beginning. If I had more time I would have redrawn the frames on the holds rather than holding the same drawing. Oh well, my teacher liked it the last time I showed it to him so I guess thats all that matters.
