00:14:928 - should be double

00:15:450 (15450|3) - should be LN? (refer 00:22:140 (22140|3) )

00:18:795 (18795|0) - I recommend moving to col5 for both playability and consistency.

00:20:154 - missing note imo

00:20:990 - should be single.

00:30:503 - All the notes on this line can be deleted imo, there is no obvious sound.

00:30:921 (30921|3,30921|6,30973|5,30973|2,31025|4,31025|1,31078|0,31078|3) - This part is even more difficult than Ultra diff. It is an obvious spike. It is recommended to delete 00:30:973 (30973|2,31025|1,31078|0)

00:31:757 (31757|2,31966|4,32175|2) - It is recommended to shorten these LNs to 1/2, like 00:32:384 (32384|4)

00:35:102 (35102|0,35102|1) - I think it would be better to swap their positions so that similar consecutive 1/4 of the entire section look more consistent.

00:35:938 (35938|5,35938|4,35938|0,36043|2,36043|5) - The structure here should be the same as 00:29:248 (29248|0,29248|2,29248|6,29301|5,29353|4), 00:32:593 (32593|1,32593|0,32593|4,32645|3,32698|2) etc.

00:37:297 (37297|0,37297|5,37297|2,37349|4,37349|6,37402|1) -
It looks weird, change to this?

00:38:029 (38029|2,38029|4,38133|4,38133|2,38342|0,38342|6,38447|0,38447|6) - I think these minijacks seem unnecessary for this section, which is relatively less intense musically, and would bring unnecessary pressure. I think this is enough:

00:49:997 (49997|1) - According to the consistency of the whole section, this note should be redundant.

00:51:722 (51722|2) - should be LN imo (refer 00:58:412 (58412|2,58412|6))
01:32:912 (92912|4) - same
01:52:753 (112753|5) - same

00:51:827 - 00:53:499
00:51:879 (51879|2,51983|3,52715|4) - There are several problems

00:52:036 - It doesn't seem to have a very strong sound, I think using double is not appropriate.

00:52:036 (52036|6,52140|5,52245|4,52245|6,52349|6,52349|4,52454|5,52558|4,52558|6,52663|5,52715|4,52767|6,52872|4,52872|5) - It is obvious that the pressure on the right hand is much greater than that on the left hand, and an unreasonable spike has been formed.
In addition, given that the actual difficulty of this part is already high, I suggest deleting these 1/4 notes to further balance the difficulty.
Suggestion:

01:33:013 - 01:34:427 same

01:07:025 - Using three LNs seems excessive. For consistency, it is recommended to delete 01:07:025 (67025|6).

01:09:643 (69643|6,69643|4,69643|0,69747|1,69747|3,69852|0,69852|2,69852|5) 01:11:315 (71315|0,71315|6,71315|2,71420|5,71420|3,71524|6,71524|4,71524|1) And so on. These LNs seem very abrupt in this whole section. I guess you are mapping the guitar sound in the background, but the whole section is actually dominated by drums, and the guitar sound is not as obvious as expected (and it actually ends at part like 01:09:956). Just a slight expression is enough.

Example:

01:34:326 - should be rice imo (refer 00:53:186)

01:44:390 - The melody has disappeared here. Considering the logic of the whole paragraph, it is recommended to delete these notes or keep only one.

01:47:526 - should be double

01:47:840 (107840|4,107840|0,107892|1,107944|2,107944|5,107997|6), 01:49:512 (109512|4,109565|5,109617|2,109617|6,109669|3), etc. These sections only feature the melody, and considering the difficulty of the other parts, the current expression is somewhat overly aggressive and doesn’t align with the intensity of the music. Specific modification suggestions can refer to the same section in the Ultra diff, using only subtle expressions will be fine.
