I didn't see it at the time I did the mix, but I get what you guys are all saying. The reason it came out so poorly was, honestly, because of a lack of experience with the program. There were mistakes that I made that can't be undone...
For example, I didn't know that not checking the "FX/Synth Automation" option when mixing would result in all the panning and effects I did being completely removed. I didn't figure out that that was the issue until I was doing the final mix, but by that point, I'd already mixed all the instruments into 1 track each. There were other lingering problems that I had from the start too, that ultimately distracted me. The guitar tone I used when I recorded had WAY too much high end to it, so much that it sounded kinda like musical static. It took a LOT of EQ work to get the guitar to the point where it wouldn't make the listener's ears vomit.
I also didn't make a back-up, so now that I know what I'm doing (well...at least a better idea of what I'm doing), there is just no way to reverse the damage I did to the song, except for recording the whole thing over again. I'm all set on that. That's why I said I'd take all the tips into account of my next song.
