00:39:105 - this finisher is mapped as a D in all other diffs so I think it'd be nice for spread consistency to keep this consistent across all of your difficulties, aswell as consistency throughout the section since it's the only one that's coloured like that even though all the sounds are the same.
The same happens in the futsuu at 00:48:480.
00:49:300 (106,107) - could move these two forward by 1/4, so the first note matches the synth sound like the rest of this section
