Great sound...but...overall it was...lacking.
The music was GREAT! I absolutely loved it. However it didn't last all the way through the flash, and that wasn't cool.
As for the cartoon itself, there was WAY too much dead space that showed just a guy...being there...not doing anything. It was exceptionally...empty.
Take out some of the dead space, shorten a LOT of the scenes, and it will go by quicker and be less boring/annoying. Plus that may make the song last all the way through which would be GREAT!
Mostly just shorten it up and it'll be good stuff.
