Hi Gary! I'm a closet disco freak...LOL I like your tune a lot. A couple of comments that may help a bit:
1. Bring up the whole level of the tune. I had to turn up my system to "feel" the tune"
2 Work on the bass line some and make it PUNCH! Same for the Kick drum. Think about the compression you're using (or NOT using...) The ProChannel has some good presets that are great "starting points" for both bass and drums.
3 I think the snare needs more "pop", so you could use a different one or layer another on top. A Transient Shaper works great for making very punctuated snares (or other percussive sounds).
4 Maybe most important, and maybe what the other guys are hearing in the mix--- While the Left/Right delayed vocals sound really cool (and I'm a HUGE fan of that technique in some applications), your main vocal should be in the center. OK to have the wide spread also, but get a voice in the center. Be sure your drum kit pieces are panned properly to accommodate the center vox. I never like the default drum kit panning on most drum kit software...too centered.
Great job on the clav/EPiano parts! Keep up the good work!
