00:00:815 (815|1,934|2) – You could improve the current pattern by changing it into 1/2 LN because the sound itself is longer than the current pattern. Pattern suggestion: https://puu.sh/GfBVG/68c5f7a526.png
Also, for the pattern afterwards, there’re 2 things that I want to say. First, 00:01:053 (1053|0,1112|1,1172|3,1231|2) - should be more complex by judging through the sound since by using the current pattern it feels a bit off, besides this is the hardest diff so you can make it harder. Second, if you accept the mod above, the suggestion and 00:01:053 (1053|0,1112|1,1172|3,1231|2) – are collide with each other so you might want to come up with something new or you can just flip it from 00:01:053 – to 00:01:886 -. Pattern suggestion: https://puu.sh/GfC6k/e20f36c641.png
00:00:815 - 00:00:934 - are changed to LN
00:01:053 (1053|0,1112|1,1172|3,1231|2) - should be more complex by judging through the sound since by using the current pattern it feels a bit off -> Actually 1243 or 1324 doesn't effect so much in harder difficulty like this set ,
00:01:053 - ~ 00:01:529 - You might realize that I'm doing stairs structure like 12 43 or 1234 so keep mod in below
00:03:275 - , 00:03:354 –, 00:03:354 -, 00:04:703 - , 00:04:783 -, 00:05:180 -they're intentionally ignored, so keep for this but
00:02:005 - I'll open this, I'll follow yours when I got same suggestion here, seems it's kinda fainter than 00:02:124 (2124|3) - this but well, it's definitely audible too.
00:02:124 (2124|3) – Because this pattern is dense already, you might want to move 00:02:124 (2124|3) - to either col 1 or 2 (1|2|3|4) for the balancing.
00:05:180 – Missing note for piano but it’s different from 00:04:703 – which only has 2 pianos (including 00:04:783 -), because this section consist of 3 pianos that you can hear using 25% 00:05:180 -, 00:05:219 -, 00:05:259 -. Therefore, I’d come up with 2 solutions. First is simplify with by changing 00:05:180 – into single LN until 00:05:338 – (pattern suggestion: https://puu.sh/GfCn3/9e3cf2c0b1.png) or just add 2 more notes at 00:05:180 – and 00:05:259 – (pattern suggestion: https://puu.sh/GfCnk/0bd5b6ed7a.png) since 00:05:219 – is kind of hard to hear so you can ignore it.
As I said on above, they're intentionally ignored,
00:02:481 ~ 00:03:196 - they actually have 1/1 -> 1/3 -> 1/1 -> 1/3 piano sound which is definitely audible with hard pitch, it's kinda awkward for me to follow 1/1 to 1/3. like back and forth
00:03:434 ~ 00:04:386 - but they kinda have 1/3 sounds ongoing,
00:08:196 (8196|2,8196|3) – should be snapped at 00:08:196 (8196|2,8196|3) – according to the patterns above 00:08:434 (8434|3,8434|1,8672|0,8672|1) –
00:25:815 (25815|2,25874|0,25934|1,25993|2) - 00:26:053 (26053|3,26112|2,26172|1,26231|0) - 얘내 둘이 같은 소리로 들리는데 통일하는건 어떨까요
00:52:005 (52005|0) – Should be stopped at 00:52:719 – and continue again at 00:52:957 – by hearing to the synth carefully. But since 00:52:005 (52005|0) – and 00:52:957 (52957|0) – are the same you can either make it as the suggestion above or 00:52:005 (52005|0) – stop it at 00:52:898 –. Both of them are okay imo but I prefer the first suggestion which most acceptable. Pattern suggestion: https://puu.sh/GfCOi/18eab43cc6.png.
01:05:874 – You could add another note for the drum. I mean, you can clearly differentiate it with 01:05:457 (65457|2,65517|1,65576|3,65576|2) –. Pattern suggestion: https://puu.sh/GfD1m/acf332228e.png.
01:12:243 (72243|3,72243|0,72243|1) – You can add another note here for more impact since this is the last pattern for this section.
fair, but I open it cuz 01:12:005 (72005|0,72005|3,72005|1,72124|1,72124|3,72124|0,72243|0,72243|3,72243|1) - they're definitely same sound
