Good
It's a nice flash, few things though.
1 - If the flash doesn't match the length of the song, edit the song down for it to fit better (in this case the first verse and then the ending chorus would have fitted better) or try to use a none lyrical song.
2 - For fight scenes, try timing certain parts of the action to time with the music (Like when the bad guy goes through the mountain would have gone better with the exact beginning of the chorus).
But it's a good flash, keep it up.
