Inward Singing Hmmm...
Good graphics, nice animation, great style.
BUT... Animating this track of Tenacious D seems useless to me, I enjoyed it a lot when listening to the album, but this animation is just unoriginal and pointless. You add nothing to the track, you just use the humor of it to get popularity.
I don't mean to be offensive or anything, just wanted to say that I want to see YOUR stuff, not someone's else ;)
Create your storyline, ask audio portal people for custom audio (I might do it as well xP), do awesome graphics (like in this one), animate - and you have might get something even better ^^
love Tenacious D btw :P
cheers
