00:51:179 (51179|3,51279|2,51379|0,51479|0,51479|1,51579|2,51579|3,51679|2,51679|3,51779|0,51779|1,51879|1,51879|0) - its quite unclear what rhythms are been emphasized in this pattern, doesn't feel to follow the chord usage you've been using the whole map. A suggestion of mine is making the rhythms like this:
01:48:779 (108779|3,108779|0,108879|1,108879|2,108979|3,108979|0,109079|1,109179|2,109179|3,109279|1,109279|0,109379|2,109379|3,109479|0,109579|1,109579|3,109579|2) - this vocal pattern repeated itself 3 times in the song, but the 3rd you mapped completely diferent to the previous two.
Same suggestions from #4489476 is appliable here
