Wow, this is excellent! You drew everything extrordinarily well, the animation was amazing, and in all honesty, I thought the music you picked went really well with the mood of everything.
And despite what everyone else is saying, this didn't make me sad, this just made me put my face closer to the screen while saying "Cooool!"
You pulled this off amazingly!
I'm gonna have to check out Vanatom now too :D
