I see this like a music for a game, like that guy below, in this song you don't need this to be quicker, you need it to be stronger.
loved that part at 3:22 keep it also some of the sound in the end, you should cut those "boring" parts a little then upload the file again and you might know mabye it will be used in some flash game.
i would like this
for a repetetive
boss stage for an action game
(Mischief Makers comes to my mind while listening this)
but in that case
i would cut some parts that are
really unnecesary i think
and loved the way it starts
