First, I just wanna mention that I don't think you're as far off from the reference as you may think you are. It's very close to it. The main differences that i hear from both are that 1) the guitars are more audible and the bass guitar is really there to support the rhythm. I don't hear really any bass in your mix if its there. Also the vocals in the reference sit just a little bit better. I don't know if its a compression or eq thing but its something i noticed. Other than that, you really are very close. Great job so far!
