Sing & Smile!!

00:04:218 (5,6,7) - ddk
There are no sounds like triple bass or melody here, ddk is makes more sense i think

00:15:107
if you want emphasis on these points, you may wanna change it to only DD-K

00:16:551
it seems to sound better not having this note mapped, maybe you could delete it

I suggest to make the finisher on 00:16:885 become a KAT
since the pitch is really high compared with 00:15:774 and a D sounds kinda off imo.

00:17:996
inconsistent finisher usage makes the emphasis weak, maybe change this pattern to dkdKK-K

00:20:440 - I guess you are missing a finisher here as the cymbal crash

00:22:663
this note can be deleted as previously mentioned about emphasis

00:24:440 (2,3,4,5,6,7) - kddkdk
consistency with 00:38:662 (2,3,4,5,6,7)

some drum notes that should be added:
00:30:551
00:32:440
00:33:774
00:33:885
I think missing some drum notes here is quite inconsistent to 00:26:774 and the section after 00:38:218
if you are try to make some density contrasts, those 5plets should be enough

00:33:774 / 00:33:885
I feel that this pattern is quite long for such a low intensity, deleting these notes would resolve that

00:39:107
change to d for consistency with previous parts, as kddkdk is the repeating pattern

00:45:329
kdkkd-k sounds much nicer since the last note is isolated (as it's a held note)

00:47:330
since the syllables are on 1/2, color change should be on there as well, so ddkdk is more appropriate

I sure get why 00:47:996 - isn't mapped, to stay consistent with the other break times, but this sound is as strong as 00:48:218 - , and it feels really empty with out a note. So I'd suggest you to get a variety in there and map that sound.

00:49:440
one note is used to represent the vocals, so I think this note can be deleted

00:52:440 - There are 3 green lines here what happened

00:56:329
one note is used to represent the vocals, so I think this note can be deleted

00:58:885 (30,31,32,33,34) - kddkk
these can emphasis ↗↘↗ of vocal, also drums

00:59:551
change K? the guitar goes up here and it's a nicer pattern

01:00:885
kdkkd / kdkkk would be ok here since the vocals stand out quite a lot at 01:01:107

01:03:107 - kddkk feels kinda off imo, maybe kkddkk/kdkkd/kdkdd/kdddk?

01:03:774 -
01:05:551 -
01:08:440
These notes should be finishers as the strong cymbal sounds
to consistent with the cymbal sound around this section
You may consider remove those vocal notes

For 01:08:440, I really think this should be finisher'ed as you placed a lot of finishers after this to present the cymbals sounds, so removing 01:08:329 would be a good choice in case to emphasize the cymbal and avoiding 1/4 finishers.

01:07:551
how about something like kkd-k-d-K here, seems to work quite nicely for build up

01:10:218 - 01:11:107
imo the SVs here would be a bit excessive as the SV gaps are kinda large
You may consider make the gap 0.5 for each
so
01:10:662 - 0.95
01:11:107 - 0.9

01:10:218 - nothing special with this sound, I think you can remove this like how Roger did.
(Accidently placed this on Roger's diff)

01:11:774
consider deleting this note as 01:10:663 k-k-d indicates that you are following the supporting melody, also makes it easier to hit the big note as you wouldn't have the problem of kK same color note

01:13:661 / 01:18:106
I think these notes do not contribute much and can be deleted

01:14:663
this is the only offhand pattern in the entire song, you may consider changing the colors

01:15:106 (20,21,22,23) - k kkd
01:31:550 (35,36,37,38) - d kkk
01:32:883 (44,45,46) - kkd
kdk pattern used about 10 times on kiai
some of points didn't follow drums, even vocal

01:20:106
no vocal change here, note not needed

01:22:439
change to d for contrast against the next note since it's noticeably different pitch

01:23:328 (27,28,29,30,31) - kkddk
01:32:217 (39,40,41,42,43) - kkddk
Too much kkdkd usage, these can make flow and more variety of patterns

01:25:550 - This could be a K to make the emphasis on 01:25:106 01:26:217 stronger

01:38:661 - I'm wondering what is this finisher for, seems there are nothing to emphasize?

01:47:328 - nothing lands on here actually so you may consider to delete it

01:53:984 - would add volume fade-outs here at the end spinner, to make the fade-out sound better.
maybe just take a look at rogers Oni, to copy the volume from there, he did that nicely-^^
