Hi I recommend reading Insane first because I modded that first and you could use many of the same advice in the other diffs
Insane00:01:075 (1,2,3,4) - Try to make this more aesthetically pleasing. Which means following a grid guideline. Also, (1) slider should flow from 00:00:700 (1) - this slider, which means the placement has to change to somewhere near the bottom
00:02:575 (2) - This slider is too long. Also, an important sound, the ”た” from "見てた" is ignored. Therefore it is better to break this slider into one note and one 1/1 slider.
00:04:075 (2) - The change in slider speed from 0.5x to 1.00x is not needed here
00:05:200 (5,6) - Consequently because of the above this note is not as long as it should be. (6) is not needed, just fix the velocity back to 0.5x and change the sliders' lengths.
00:04:825 (4) - Nice that you noticed (2,3) sliders that come before this should have similar shape, but this (4) slider should not be a slider at all, I feel it is more appropriate for it to be two notes as there are two syllables from the vocalist.
00:05:950 (8,9) - The gap between these two is too big.
00:08:200 (6,7) - I know you're trying to repeat the same slider shape to show the piano being played, but when you have to break it and put more suitable notes you should. I think this is better replaced with two single notes instead.
00:08:200 (6,7,8) - Make sure the gap between (7) and (8) are the same for consistency.
00:08:950 (9,1) - The gap between this two should be bigger
00:11:200 (4) - This note should have a new color to show a sudden change in music. (Extra: This is the time to show a bit of creativity and change the shape to something sharp but readable. Go for some fancy shape instead of a straight line. This is also because in other calm parts of the song you use straight lines so there is a slight contradiction.)
00:11:200 (4,5) - The gap between this two should be bigger (consistency)
00:11:575 (5,6,7,8,9,10) - This pattern is not aesthetically pleasing due to the inconsistency in the change of spacing. I get what you're trying to do, but for nicer stream shapes, try creating a slider where the stream should be, and then selecting the slider and using Ctrl+Shift+F to change it to streams.
00:11:575 (5,6,7,8,9,10,1,2,3,4,5,6,7) - For the stream as a whole, the wobbly noise increases in pitch every 4 notes, so I recommend a new combo color for every four notes. This is also convenient and appropriate to use a spacing increase every four notes.
00:13:075 (1,2,3) - Inappropriate spacing
00:13:825 (3,4) - Spacing too large
00:14:950 (7,8) - Spacing too small
00:16:075 (2,3,4) - This spacing is good. Not really happy about the shape though
00:17:388 (6,1) - You're missing an important note between these two
00:18:325 (2) - This slider should not have the slower slider velocity (consistency)
00:19:075 (3) - This should be a new combo
00:20:013 (8,9) - The gap between these two is rather sudden, so an appropriate change would be to put slider (9) somewhere at the bottom
00:19:075 (3,4,5,6,7,8,9,10,11,12,13,14,15) - This whole thing should not have just one colour
00:21:700 (1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,5,6,7,8,9,10,11,12,13) - There should be 7 colors total here, with the last note being the single (1). Also, make the stream shape nicer with the suggestion I made earlier.
00:24:700 (2) - Symbolize a change in music and slider velocity with a new color combo
00:26:575 (2,3) - The gap between the slider end of (2) and the head of (3) is too big
00:27:700 (6) - This should be a new combo
00:28:450 (8) - The decrease in velocity is too drastic, something a little higher than this but lower than the common one used for this section. Also, change the shape and show your creativity
00:29:200 (1,2,3,4) - This is viable, but not if (3) and (4) directly overlap (1) and (2). It's ok to put them under each other, but they must stick out slightly and equally to make it easier for the player to read.
00:29:950 (1,2) - Aesthetically displeasing when you put it there
00:30:325 (2,1) - Spacing is too large
00:32:200 (5) - This should be a new combo
00:32:950 (7,8) - (7) should not be directly under (6)
00:33:512 (9) - Hard to read here
-Too many things to comment if I have to nitpick everything, so I hope you see what I'm pointing out and fix the rest of the song. From now I'll only pick out glaring errors-
00:55:075 (2,3,4,5,6,7) - Don't ignore the sounds between
01:38:575 (1,1) - Just no
02:01:075 (1,2) - For this section in general with the electronic backgrounds and stuff. Don't focus primarily on the vocals, you can display creativity and show the electronic parts with sliders as well.
