Well don’t get me wrong it’s a darn good mix and whatever samples you are using sound utterly fabulous. The dynamic contrast is a bit much I think, consider the piano note at .21 seconds, it almost made me wet myself. I would have probably reigned it in with some light compression and probably wouldn’t have had the drums quite so up front when they were first introduced.
Still, you’re a very talented dude and the music is good so that’s what counts. 
The mix is good too, like you say everyone would do it differently.
