Spooky!
Well done on your first upload. It may not have been your first movie, but meh.
This seems (to me anyway) to hold all of the creepy...ness of the original movie. It had that kind of heart grabby feeling which I hate. The sounds added to the movie well, and I think you did them just right. Graphics were fine, though the character models could use some improvement, I think, (particularly with the eyes, which to me looked more funny than anything. Then again, they are pretty hard to draw well.
Another thing which lost some marks is lack of originality, as you didn't add much to the original video. You did well on it, but I like to see more added, really.
Other than that, it was a good first effort, and I hope to see more development in the "long version."
Good luck!
