A pretty good start.
I, too, can't really hear the vocals well enough. Could you run them through a compressor or boost the volume a bit?
I like the guitar sound, very raw. It could still benefit from a bit of softening, maybe a deesser to clean up some of the gritty 8-16k clicking, that should make them a bit warmer too and you could boost them up 1-2db more.
You have a fat bass track to work with, which sounds pretty good, but roll it off between 90-120hz and see how that plays for you.
