Use the original as a mix reference maybe?
Your vocals are very good (wish I could go that low- I'm stuck with the Jeff Walker voice for better or for worse), but maybe add a bit more compression to them, they sound a little plain in that regard (could also be your delivery, maybe add a little more ferocity and energy to it- in short, be meaner and more pissed off). The guitars are very flat, not enough low end on those.
Other than that, I'd say try to balance everything a bit more volume/eq-wise, seems like you've got the performance part of it down pretty well.
What drum procress are you using (real, MF, AD, SD2.0)? IMO thyis is the weakest link, they add no power to your recording, needs moar powah!
