A good start to animating
Let me start off by saying that I did not see that ending coming. The ball looked pretty good and had some nice animation going....but this was more a sprite movie than anything else. I liked the concept of a ball just going around doing whatever and messing with video game characters and then having them chase after the ball.
For one, the dialogue you had in there I couldn't really understand and what I did understand it wasn't very funny. It sounded like somebody just behind the mike doing voices, not the characters talking if you get what I mean. And some of the music clips seemed out of place(they went by too quickly and just didn't mesh with the movie).
The sprite animation was really smooth and nice. What I would say is work on your own drawing skills so that way you can combine the sprite animating with your own drawings ( the Tankman series is a good example of that). I think good things will happen if you head in that direction.
Just keep making stuff man! You have potential. I stuck around to watch the ending of the animation so it has something to it! You also have a pretty good score. Just keep making stuff!
