just commenting on how different these two versions are. I was looking around here for the first time in a while and listened to your first try and then the new one right after. It is sounding much better, especially the bass. I very much enjoy what you did to the bass.
that said, I think that this mix still tends to drag at parts. There are parts that seem repetitive when you have the melody going. Maybe adding a counter melody with a different instrument, or even the same, when you have melodies repeating. Having a counter melody or harmonies could help take out the repetitive feeling that I'm getting. There was a section towards the end where you did repeat the melody with a harmony and it made it sound like less repetition while still being the same thing.
anyway, I still am blown away by the growth between this and your first shot at this. good luck with this one
