I like your song Sean, but the vocals are a little pitchy in places.
Drums on a song like this require punch. This sounds like a live kit, recorded w/mics? If it is, there's still a lot that can be done to help them.
When it kicks in to a strong Guns n Roses vibe? I would lose the acoustic and bring in another distorted electric. And the electrics feel buried in the mix to me (the rhythm guitar)
You need to love on this mix a bit... Not sure what tools you have available, in terms of compressors, limiters, exciters, vocal editors, transient shappers, etc... "Colossians 3:14" Love on this mix...
