I think I know.
This animation was certainly creative enough, and is one of the better entries of the gost project I have seen, but as with many animations you suffered from a lack of proper implementation. The animation itself would've been 10 times more interesting, if you had the camera switch angles, and change periodically during the Gost's speech on what a ghost was. I found a subtle piece of irony in that he was giving the speech, which was quite enjoyable, but the physical lack of motion on the screen failed to keep my interest. As a matter of fact it failed to keep my interest to such an extent I could not even finish the entire animation. If it turns out that my overall review is biased due to this - i.e. something amazing happened right at the end - tell me, and I'll vote a 5 on this the next day as pennance.
In any event I think I know your response. You are going to be upset that I disliked your animation, but then you are going to completely disreagrd what I have to say becuase I have submitted no animations, then you are going to make the same mistakes over, and over, and over and over...
Oh well.
