Battle Against a True Hero

00:06:030 (6030|3) - sure this cant be intentional? i dont see why you cant connect the LN

00:06:412 - 00:08:012 - maybe it's better to put them in the different column since it have different sound composition, like on 00:06:412 - is have some extra sound (just to make a different feelings and variant plays, since you've use very repetitive pattern here)

00:18:830 (18830|2) - you use LN for piano when it clearly goes past it
adjust any other LN like this

00:28:400 (28400|0) - how about on moving this note to col 2? if u zoom out col 2 is a bit empty

00:31:012 (31012|1) - 如果你在这里使用 3 个连续的 ln，那么会破坏一致性，因为前后类似的地方都是 2 个连续的 ln

00:40:600 (40600|3) - I Think this object (or any other object close to it) should be placed in the first column because the first column is empty if you zoom out.

00:44:800 how about on making this double for cymbal?

00:44:830 (44830|1,44830|3,44830|2) - Accoring to RC: Avoid chords with more than 2 notes. This includes long note patterns that involve notes in more than two columns. However, using a double that is played with the other hand than the long note is fine.避免使用多于 2 个物件的多押。 也尽量避免使用同时占据多于 2 轨的长键。但允许当一只手按下长键时，在另一只手负责的按键上放置双押。
你可以把这个note 00:44:430 (44430|0) - 与00:44:830 (44830|2) - 交换一下位置。这样左手便能负责jump,右手负责LN了。也不会违法RC。

00:45:600 - 01:36:000 - The jumps in this section are a bit boring, they feel rushed and done just to fill in the gap, I think it'd be better if you map the melody (with singles) that sounds in the background since it is more audible and more interesting rhythmically than the snares

there had a rc said "Avoid rhythms faster than 1/2 during a 1/1 long note's hold duration."
that means you can't put notes with 1/4 gap in 1/1 or longer LN in normal, so 00:45:612 (45612|3,45712|0) - 00:45:612 (45612|3,47312|2) - something like this is not proper in this diff, please fixed this issue in this whole section from 00:44:812 - to 01:36:012 -

00:47:030 (47030|1,47030|2,47430|2,47430|1) - i believe it would be best to shift it over to keep consistency with the snare on the left hand

00:47:630 (47630|0) - and the put this to col 4 since it would fit the music rising

00:52:230 (52230|0,52230|1,52630|1,52630|0,53030|0,53030|1,53430|1,53430|0,53830|0,53830|1,54230|1,54230|0) - i think this is a little too heavy on the left hand
making it jumpstream would distribute the weight balance between both hands

00:56:430 (56430|1,56630|3,56630|0,56830|2,57030|1,57030|0,57230|2,57430|3,57430|0,57630|1) - coming from 00:52:297, you should distribute those notes to both hands for balance purposes

00:57:600 i think u missed a note here, a 3/4 Ln to be precise for the string sound

01:16:612 (76612|0,76812|0) - put them to different column, for consistency with 00:51:012 -
and i think this time is different case like 01:03:812 -

from 01:29:600 to 01:36:000 you map to those string sounds but I think it would fit better if you mapped to the drums too

01:36:000 to 01:55:200 why is this kiai? This section isnt the most intense or even intense part of the song

01:40:812 (100812|3,101012|2,101212|1,101412|2,101612|0,101812|2,102012|3) - rc not support to use 5+ 1/2 rhythm in normal but here is 7x, I think this can work since the melody pretty continued in single stream, also 150 not 180. So here shouldn't be a problem BUT BASED ON THIS
-
02:24:012 (144012|0,144012|1,144212|2,144412|3,144412|0,144612|2,144812|1,144812|3,145012|2,145212|0,145212|1) -
this is unrankable 2-1-2-1-2-1-2 with 7x is totally break the RC, so simplified or nerf the chordside, it doesnt matter what way you use but this defo can't be work in normal. Keep this setting in other higer diff but NO here.

01:42:000 (102000|2) - i suggest moving this to col 4 so it doesn't create a jack with the note before

01:43:400 (103400|1) - This note doesn't seem to follow the melody, the same happens with this one 02:11:000 (131000|1) You should delete them

01:44:200 (104200|0,104300|1) - these should be rice notes, i dont think players at this level will handle 1/4 long notes

01:44:200 (104200|1,104300|1) - this sounds more like a little glissando to me, so i think its better to represent them as a stair

like this:

01:44:262 (104262|0,104312|1) - RC 能用？

For me I think the KIAI Part is too weird to play.

01:55:230 to 02:14:430 - you can do like this to fill gap with Hard diff
https://osu.ppy.sh/ss/19395765/79d9

02:14:430 to 02:33:630 - you can do like this
https://osu.ppy.sh/ss/19395781/54a1

01:58:212 - start from this, it's have some spread issues because easy diff is literally harder than normal diff (because you've put some extra notes on easy, but not at normal diff) https://osu.ppy.sh/ss/19409771/01a1

02:03:612 (123612|1) - 如果太挤了，就往1或者4轨放，不然 02:03:512 (123512|2,123812|2,124212|2,124612|2,124812|2) - 密度太大

02:03:612 (123612|3,123612|0,124812|2,124812|3) - all the similar part like this can be added some 1/1 note to make the LN duration not that empty, not cuz this the must thing you do, just your Hard got very dense objects so you should make a better spread from easy to hard.

02:03:800 (123800|0) - This object should be placed here 02:03:600 - Also, the song makes a glissando and you should represent it with a stair for consistency the same thing happens here 02:22:600 (142600|2) -

02:04:800 & 02:05:600 why these 2 are not doubles but the others do like 02:00:000 02:00:800 02:19:200 02:20:000
i think u should double them for consistensy

02:10:200 (130200|2) - how about on making this a Ln? cuz sounds the same as 02:10:400 (130400|3) -

02:10:800 (130800|2) - i think u should extend this Ln duration to 02:11:200, bc the sustained sound is clearly larguer

02:22:662 (142662|1,142737|2) - I think this should be in 1/4 like 02:22:612 - 02:22:712 - , 实际上可能有一个02:22:662 - 但是因为低难度可以忽略简化

02:31:200 (151200|2,151200|1) - how about on reducing this Lns to 02:33:600, i think it would play good
