It has potential...
Good work for your age. I do hope you’ll continue to develop and polish your style.
It moved well at the beginning, even though most of the plot was taken from the action of the first movie. Try creating your own ‘adventures,’ rather than taking them from the movie or the book.
The ending was rushed and didn’t really make much sense.
Overall, practice developing your own plot. Your animations are decent, but they need a good story to compliment them.
As for the music, it would have worked better if you changed it to suit the action. Just sticking a piece from the movie soundtrack and letting it play really doesn’t work.
All the same, nice effort. Keep it up! ;)
