I think the initial sound you have as the intro is cool, but it could be quieter or compressed a little. You could send the bass to a bus (or duplicate the track) and distort it and hi pass at around 1k, but take it down like 20 to 30 dB to add clarity - what you have does suit the genre though and this is more of a personal preference. I also think you could pull the vocal volume down too so it's not so much on top of the rest of the music, but sits inside it. You could bring up the acoustic a bit more too and take a touch of reverb out of it to get more rhythm. I'd be tempted to experiment with changing the formant on the vocal a little and maybe pulling 1.5 kHz down a little to make it sounds smoother and deeper for this song, but pulling the volume down a bit might have the same effect. I might also hard pan the organ left and right to make it feel wider if you recorded that in stereo. The bottom end sounds wonderful and the rest of the mix is very clear overall. Great song!
