Yea, definitely a much more improved version!  good transitional sounds and fx. its arranged pretty nicely and keeps me interested.  great work! 

the piano melody could use work to really make it special, but it honestly doesnt have to change because it works, doesnt have to be a complicated melody 

oh yea, and that "howl" sound that you use is hot, but use it much less in order to keep its effective impact on the listener.  it sounded over used.

keep up the great work 

You could maybe go a little heavier on your bass in the drop sections though, maybe add a low-mid layer like a filtered reese or something.  It sounds like it could use something to fill the gap between your saws and your sub maybe.
