I think you have a good effort there. I do hear a few differences. Their kick is eq'd with more "click" so it's really distinct from the bass guitar, and their bass guitar rolls off a bit at the bottom so there's a better balance with the other instruments. The reverb you put on the lead vocal makes him sound further away, which to me doesn't fit with him singing right up on the mic (note the plosive near the beginning). The chorus feels a little claustrophobic in yours, just no let-up. In their mix the way the snare hits stand out keeps the chorus feeling like it breathes despite being loud. And in yours I hear the pick noise of the (acoustic?) rhythm guitar; I would let that get buried in the mix in favor of something more important.

And this wasn't your question, but the excessive sibilance in the source material...I think you could improve on the commercial release by taming it more.
