This is actually really good, especially for a newbie. It would have been nice to get some sound effects, color, and backgrounds going, but the most important part of animation is smoothness and you captured that pretty well (particle effects could use some work.)
Midway through watching this I realized it would be really cool if this animation were one continuous slow pan across a landscape showing all of these animations next to each other, like the faces being foreground, a guy sawing wood in the background, maybe even have the swinging arm positioned so it looks as if it's dribbling the ball. Linking everything together would have made this look really, REALLY nice.
