02:11:095 (97,98,99) - i understand the build you do here, but i think this is better as kkk to make it the same to the other triplets. it's a really long stream and it will be a good way for Muzukashii player to start adapting to hit triplet, but with the same color. if you're against it, then i would suggest you to change the pattern to ddd-kkk-ddd-kkk instead of ddd-kkk-kkk-kkk
Same concern as Futsuu, there are some parts that needs break here. Example is 01:11:095 (284,285,286,287,288,289,290,291,292,293,294,295,296,297) - , the pattern is too complicated and there's also a 3/4 which makes it more complicated. I'm not against 1/2+1/4 at the same section, but sufficient breaks is also needed.
In this case, you could separate them into two parts, and my suggestion is this kind of pattern https://osu.ppy.sh/ss/16999015/198c, which is acceptable for Muzukashii.
you can see that i changed the first part to kdkdk, and that's to give example of a simple pattern. It's actually up to you, but if there's 1/4 in the end then i would suggest making it simple like ddddk/kkkkd/dkkkd/kdddk/dkdkd/kdkdk/etc, the type that would be easier to read and to hit.
01:06:440 (264) - i suggest removing this note because this actually overlapped with 01:06:267 (263) - , which makes 264 a bit of surprising and might make player miss
00:34:371 (119) - i'm actually a bit surprised by this note because you were following the rhythmic music, not the drum. i suggest removing the note and just add a kat 00:34:198 to make it more consistent with the music
The Futsuu diff you're making right now is too dense to be a bridge between Kantan and Muzukashii. Some parts are too dense, that it resembles easy Muzukashii too much.
For example 01:25:577 (255,256,257,258,259,260,261,262,263,264,265,266,267,268,269,270,271,272,273,274,275,276,277,278,279,280,281) - this part contains too many 1/1 and 1/2 patterns, that it looks like this is Muzukashii. There should be a few breaks here and there, like 1 https://osu.ppy.sh/ss/16998828/9c31 and 2 https://osu.ppy.sh/ss/16998863/10b4. this will give sufficient 2/1 breaks between patterns.
not only those kind of patterns, this too 00:52:819 (141,142,143,144,145,146,147,148,149,150,151,152,153,154,155,156,157,158,159,160,161) - is kinda concerning for me, because there's no breaks especially after the 1/2s and the note and pattern changes there, so it might be confusing and tiring for new Futsuu player.
what i suggest is:
01:07:474 (96,97) - remove 96 because 1/2 kD is too much on kantan, especially with 150+bpm. you didn't do the same pattern with 02:57:646 (which sounds more complex, i think)
