Well, you might start by starting over with each track and panning things out more. It sounds like every thing is on top of each other. Remember you can pan left and right 1 - 100 on each side, so there is plenty of space. Also left and right you don't want things sharing the same space. Example drum beats #1 @30 left, drum beats #2@ 35 right, cymbals #1 @ 38 left and cymbals #2 @ 40 right, and so on and so forth. Vocals @ 25 and back up vocals @ 45. The spread depends on where you want each track placed in the mix. Then you can also control the volume for each so that each track is heard clearly in the mix. So on and so forth. It is time consuming but in the end it pays off. Also, when using presets for the final mix, you really need to understand each presets settings, as each setting will alter you tracks. Then consider the amount of reverb you want, if any, echo, excitement, dynamics, equal or unequal, stereo expansion and so on. It doesn't come overnight, but stick with it, sounds like you might have the beginnings of a good song here.
