I listened to all the mixes and I think Mix 2 has the most potential. The vocals are obviously way too low and thus become almost secondary in character which just doesn't work for a singer-songwriter type of thing like this song is. Having said that.. everything else is super nice! I really like the "dry" feel of all the instruments and how you've minimized annoying frequencies yet retained the original tonality of the tracks. Very well done!
Mix 3 is a bit odd. I see you tamed the overall bass frequencies quite a bit (which is a good thing) but combining this with the slightly "cold" plate like reverb of the vocals makes the overall cozy feel of Mix 2 disappear.. which is why I prefer it less. The vocal level here is much better though.
I'd say Mix 2 + vocal level boost (may need up to 2dB of boost) would give an almost perfect mix for mastering. I wouldn't worry too much about the overall amount of bass in Mix 2 because the instruments containing bass are all in very good balance so it's an easy task for the mastering engineer to simply tame this with a subtle low-shelf EQ without losing any of the natural feel of the mix.
