1. Widescreen Support is unchecked only for Insane. Make sure it's checked or unchecked consistently for each difficulty as you intend.
2. If you don't plan on having a storyboard, you can delete the .osb to reduce the file size.
3. There are several unneeded green lines in each difficulty.

1. 00:10:600 (5) - Remove the finish on the reverse. It seems unnecessary because a low beat sound is more prominent and still sounds good without it.
2. 00:13:171 (3,4,1) - The consecutive finishes is cool but it's a bit strange to hear finishes on sounds in the music that are so different or don't even have a sound on them. See if you like this instead: Swap the finish on the tail of 00:13:171 (3) for a drum-whistle to emphasize the heavy beat and remove the finish on 00:14:457 (4).
3. 00:17:885 (3) - Remove the finish. The sound you are using to emphasize with finishes (using the tail of 00:15:742 (2) as an example) actually lands on 00:18:100 so having it here sounds strange.
4. 00:22:600 (2,4) - The high sounds in the BGM that are on both tails of these sliders would sound great with soft-whistles. Try it out~
5. 00:35:457 - Feels strange to be starting a spinner on such a significant beat. I would add a note here to catch it, start the spinner immediately after, and swap the drum-finish from 00:35:028 (3) to the new circle.
6. 00:40:600 (3) - Not a fan of the reversing 3/2 slider. It makes the most sense with how the music is like for 01:18:742 (4) and the ones that follow, not so much here. Having feedback on 00:41:448 whether clickable or not is going to feel most intuitive for beginner players and reversing on the red tick might throw them off because of how you've been following the music up to this point. I suggest you keep your rhythm entirely on white ticks for this part.
7. 00:46:600 (1,2) - Try drum-finishes on the heads instead of normal-clap, I think it would fit more nicely.
8. 00:49:171 (1,2) - Same as above.
9. 01:02:028 (6) - I would prefer you swap the hit-sounds here so it's the drum-whistle on the head to fit the sound better, and having a drum-finish on the tail would be more consistent with your usage of this hit-sound (like at 00:44:457 (2) as an example).
10. 01:29:028 (5) - Soft-whistle here fits nicely.
11. 01:37:600 (1,2,3) - Spacing is a bit wonky between these three. You can clean it up for a perfect triangle shape.
12. 01:45:313 (2) - Whistle on this one is a bit strange because the sound you previously used to emphasize with a whistle is now on 01:45:528. I would remove the whistle so it doesn't feel out of place, as well you could adjust the rhythm here to catch that sound as another option.
13. 01:46:599 (5) - Same suggestion as 00:10:600 (5).
14. 01:49:171 (3,4,1) - Same suggestion as 00:13:171 (3,4,1).
15. 01:55:171 (2) - Finish here seems unnecessary and doesn't bring out anything in the music. I would remove it.
    
    Mostly hit-sounding suggestions here and I suppose they can apply to the other difficulties as well. I may repeat some for the other difficulties but I would refer back to this.

1. 00:35:457 - Same suggestion as Easy, this heavy beat really deserves a note.
2. 00:37:600 (1) - I would prefer to delete this note just because of how shortly it follows after the spinner to make game-play more comfortable for beginner/amateur players.
3. 00:44:885 (6) - Whistle on the tail would sound nice with how you used it on the tail of 00:43:171 (2).
4. 00:48:314 (3) - Spacing inconsistency here.
5. 01:45:314 (4) - Since the whistle sound makes more sense to have on 01:45:528 for the reason I mentioned in Easy. Maybe break this up into a circle and 1/2 slider so you can emphasize the sound there.
6. 01:57:742 (1,2,3) - More use of 1/2 sliders in the rhythm here fits more with what's going on in the music in my opinion. Try this out:
   Example

   

1. 00:19:064 (3) - Remove whistle on the head and change the finish on the reverse to a drum whistle if you would like. The whistle and finish so close together is quite noisy and doesn't sound great.
2. 00:20:350 (3) - The big volume increase back to 100% kind of makes the drum-whistle on the head feel like it's too suddenly loud and out place. Perhaps increasing volume to 90% to make it stand out less?
3. 00:32:885 (3,4) - Shortening (3) to end on the red tick and extending (4) to begin and end on blue ticks I feel follows the vocal more accurately here.
   Example

   
4. 02:00:100 (1) - Remove NC might be good here since this part and the previous combo are musically identical.

1. 00:19:064 (3,4) - I would give a bit more spacing between these two to make it easier for players to read the 3/4 gap. The current spacing is similar to 1/2 rhythms seen previously.
2. 00:35:457 (10) - Because this note isn't attached to vocals like the previous ones, maybe you would like a NC on this? I think it'd be a nice effect.
3. 00:43:171 (3) - Perhaps you can make this blanket the approach ring of 00:42:957 (2) more nicely?
4. 01:45:635 (1) - Not too keen on the use of a 1/4 reverse here. I think it would be better to just have a circle on 01:45:742 to get the most emphasis on that heavy downbeat. Also it would lead more nicely into the 1/2 rhythms that follow.

1. finish spam.. are you sure?
2. 00:19:171 (2) - For Example this, really not fit finish. clap more fit imo. you reconsideration hitsound.
3. 00:20:457 (4) - add finish slider end?
4. 00:45:742 (4,1) - switch NC?
5. 00:56:885 (6) - Add NC.
6. 01:02:028 (6) - Additons Auto and add clap. and remove finish. (same 01:00:314 (3) - slider head)
7. 01:13:171 (1) - Add finish? because 01:06:742 (1) - same sound.
8. 01:23:885 (1,2,3) - try make perfect triangle. (also, bit bad spacing now. 1.01→0.97→0.93) (2) move (x:257 y:16). (3) move (x:273 y:104). so, all 1.00 spacing.
9. 01:29:457 (6) - Additons Auto and add clap. and remove finish.
10. 01:37:600 (1,2,3) - try make perfect triangle again. so, before suggest copy please.
11. 02:04:600 (1) - add clap slider reverse.

1. Oh, CS4 Normal
2. 00:11:457 (8,1) - switch NC.
3. 00:50:885 (3,4) - please perfect stacking.
4. 01:11:242 (1) - add finish? your pettern imo.
   rere Normal CS4. i love this diff.

1. 01:24:314 (4) - bit overlaps. move bit left?
2. 02:02:028 (1) - add clap slider head.
3. 02:05:457 (1) - ^
4. 02:08:028 (1) - put (x:256 y:192)?

1. HP9 is sure? really high imo. try 8?

12:42 Sieg: говорю же
12:43 -Bakari-: 00:53:028 (2) - вот этот серкл и все другие отодвинуть бы от предыдущей (4)
12:43 -Bakari-: новички могут случайно проигнорить (1) и сразу кликнуть (2)
12:43 Sieg: а вроде нормально
12:43 -Bakari-: просто потому, что (2) близко
12:43 Sieg: ну хз
12:43 -Bakari-: https://osu.ppy.sh/ss/1504019

12:44 -Bakari-: 00:56:885 (6) - sounds totally different, would use NC here to emphasize sound changes
12:45 Sieg: можно
12:45 -Bakari-: 01:20:456 (1,2,3,4) - чертовски годная копипаста. <3
12:46 Sieg: там сложно что-то по другому сделать
12:46 Sieg: на самом деле
12:47 -Bakari-: 01:49:171 (3) - попробуй заменить на 1/1 слайдер + серкл, этот клэп как-то отдельно звучит, мне кажется
12:47 Sieg: ага

спасибо няша
изменения все чуть позже

1. 00:51:742 (4) - Stack can be confusing for beginners but it's up to you
2. 01:32:456 (4) - I think this slider isn't in rhythm !
3. 01:38:778 - Resnap a greenline here

1. 00:05:457 - Add a note ?
2. 00:05:885 (2) - Inconsistent spacing
3. 00:21:742 (1,2) - Maybe make the same slider ?
4. 01:30:313 (1) - Curv it maybe ?
5. 01:44:028 (1,2,3,4) - shape of parallelogramm can be improved !
6. 01:50:885 (1,2) - You can better stack !

1. 00:26:028 (1,2,3) - Idk why but these sliders looks akward when I'm playing it
2. 00:33:742 (5,6) - Pretty bad overlap
3. 00:50:885 (3,4) - You can better stack
4. 01:58:385 (2,3,4) - Make a double instead of a triplet

1. Haven't found anything but I notice a lot of weird sliders !
   That doesn't mean to remap but some sliders are weird ! Like this 01:00:314 (3) - , 01:01:385 (5) - or 01:08:885 (7) - .
