Turn every channel right down, then bring the kick up to -5db.
Bring the snare up so that it sounds about right.
Bring in the bass and don't let it clash with the kick - if it does, start EQing out frequencies that overlap between the two.
Bring up the other instruments so that they can be heard and begin panning them so that they sit in their own locations and things sound balanced, but not mono.
This should keep your mix down to a much more suitable level.
Not one fader on the centroid has been adjusted in the snapshot. There are no more than 3 EQs being used, and not a single compressor.
Then there's the horrendous clipping..
Mixing is the art of balancing all the elements of a track so that they all sit comfortably in their own space in the stereo field, frequency spectrum and dynamic range. At the end of mixing, you should be getting roughly -6db out of the mixer so that there is ample headroom for mastering.
