its ok but you can do it better!
practice everyday on the dimentions , and try to put a litle more action on your animations...
Mediocre at best but...
...you have potential. Keep practicin'.
Also, it would have been cooler if you made the movie "loop"...like when the fish got caught in the chest, you make another fish come along, starting the whole movie over again. Does that make any sense? God, I hope...
But it needs a little work. It's very simple. Try adding something that makes people say Wow!
The plot is that this should be looped. The fish opens the chest to find some air and another fish of the same type dead in the box. So, when the box closes, that means that that fish is the next fish to die! lol, its so simple and great! Great job!
