Thanks for the input guys. I realize it's very mechanical sounding at the moment. I haven't done very much with that yet except in parts where it was really bothering me. But I'll look into that guide stevo wrote because I'm probably not very good at it.
And Nostalvania, thanks for your in-depth chord analysis. I'll try your ideas out to see what they sound like. I'm not so good with chord structures and music theory in general so I wouldn't be surprised if there's something a little off sounding that I didn't pick up.
Any advice on other mixing techniques to get a better sound out of it? Any instruments that stand out as to dull sounding?
