RE "Follow you down" - that's a big fat bass sound! It sounds as though you have some sort of stereo doubling going on which cuts in and out at the end. It's quite jarring on the ears, but I guess that was done for effect? Cool song anyway!
If you wanted tips on the mix... the snare sound could be bigger, maybe longer reverb, maybe just some more top end. The cymbals don't sound particularly natural but I guess you're restricted to your sounds. The synths don't seem to fit that well. Some of it sounds like pretty cheap string sounds. There's a hammond type sound at the end which does fit the music pretty well, so maybe try the other parts with this sound? Also I would copy your vocal track, distort the hell out of it, and then bring this in and out with the loud and quiet sections.
