I listened to your latest mix.
Sonically, I think it sounds good. I don't mind the reverb amount, or its timbre. I like the panning to. I wonder if the organ sound is contributing a bit to the low frequency mud? I assume you have already tried some low end roll off, and other low mid tweaking?
I agree with HumanPlanet that it needs retracking due to the pitchy vocals. The guitar sounds slightly out of tune to me, as well.
Overall enjoyed the tune.
