ok.
here's whatchu gotta do. You gotta get some sort of audio editing software (I use audacity - google it. It's free and you can get heaps of good plugins for it, probably most notably the LAME mp3 decoder/encoder)
from here, you need to edit the mp3 file (or whatever file type you're using for audio) and dear god, you have to cut it down to the time that you're using it for. This is what potatoscrub was saying before, and I actually find it helpful.
Apart from that issue (making the file size ridiculous for the actual time spent watching) it was alright. You should work on making the animation generally smoother and such.
I'll give you a 7 for your efforts - you had some nice artwork, particularly the still of the werewolf.
