Good Job
Realy good.
Some of the motion is realy nice. The part where he fell down looked great, the curve of his back and the position of his legs where realy good.
The part where he walked was nice.
Walking is, as you know, one of the hardest things to have look right.
You little guy walked nicely, he had sort of a "cowboy" look to his walk.
The bit where he rubbed his head was nice and moved well.
One note: He should have had a face from the frist frame.
Keep it up, you have talent... I can tell.
Try to flesh them out a bit more on your next few projects.
Cheers!
