This was not bad. It seems like you're more of a story teller than an animator. While the story was good, I felt it was a bit too overdramatic at times. Especially near the end.
Also, while it's good, there really was very little animation to speak of. If there was a category to rate on just animation, I would have to give you a low mark as not a lot of work was done in that area.
One other thing, when you said "Their coming back" It should be "They're coming back." Haha, sorry, I'm picky about grammar.
However, overall it was good and I defintely did not give this a blam grade. 2/5 from me.
