So you like critique, eh?
Well this mix was pretty cool, despite the fact that it was sorta short and didn't go anywhere. You're most likely going to lose points on sound quality and on the lack of ending.
And there's no bass! Bass is really what holds a song together, mate.
You should work on your mixing skills, add some stuff to this and then resubmit later, because at its core it really isn't too bad.
Rated 4 for potential :]
