Do you come from that community that specializes in video editing? I saw winners of the contest. Really nice.
I saw your AMV but I mean shouldn't there be good coordination between sound and visual elements? I think you should work on that.
That is the only thing that I can say sadly because I am not really that knowledgeable when it comes to video editing.
But good job! Video editing is hard-working task to do. That I know for sure!
