Awesome
I really like the way you bookended this! And when I read "pitched up" I thought, oh no, another Alvin and the Chipmunks tribute...but it really dosesn't have that feel, and you ge tthe whole song. The one thing I'm still not sure on (after 40+ views) is the scene where the character is floating and has an energy charge around him. I assume this is the main character, but the main character always sings and appears melancholy (blue) throughout. Red is indifferent, almost stoic (capturing the song's mood well) so I don't know who it is blowing up the castles, and frankly it almost interrupts the overall flow.
Besides that, a great work that I won't get tired of any time soon!
