I agree with the title...
but this video made me feel that there was something lacking. Whenever I hear the word "Epic", especially if it's neatly advertised as such in your title, I expect something epic. This video was anything but epic. I felt that it was always building up to something greater, but the short animation length just killed it. I would recommend (if you ever decide to) that you add a bit more length, a bit more flashy colors, explosions maybe? (explosions are always epic), and better font for the ending of your animation...a font that reeks of epic-ness ...not some plain Arial stuff. Mkay? However, I did give you some points for the music, for I must say, this type of music was a great choice to work with. But remember, since you are making an animation OF music, your animation must be up to par with your audio, maybe even better.
