Gary, there is a point I'd like to make about your song. Rather that get too specific, I want to mention mostly concepts and let you figure out how to implement them, but a small suggestion to point you in that direction.
Section differentiation: Not meant as a criticism, but without the lyrics I wouldn't be able to tell the verse from the pre-chorus, from the chorus, because you use the same drum and guitar sounds for all the sections. I realize that you're not gonna change drum patches but for example, most choruses use a ride cymbal versus a high hat for the verse. What you want is a scene change. On the pre-chorus I kept wanting to hear a clean guitar doing an arpeggiated walk down but with that section ending on a 5 so you could go back to 1 for the chorus. Ending the pre-chorus on 1, and then going to the chorus on the same chord seems to not go anywhere, if you see what I mean.
Feel free to disagree, or ask questions. You made a good effort and a very clean recording.
