I got to say, this was boring to watch. The music is okay, animation is great, idea is good, but somehow it doesn't really work.
It seems to me that the cartoon is not sure if it is it's own thing or a music video. It sits uncomfortably in the middle.
And if it is music video then there was no need for sound effects. It is distracting, especially when it doesn't help to give explosions and punches that, how should I call it.... kicker, I guess.
Good idea, average execution.
But art style is great so I encourage you to keep expanding and working on it :)
