  Everything which is not hitsounds orz:

1. 00:19:009 (3,4) - This sounds somewhat weird, because the emphasized sounds are actually 00:18:844 and 00:19:174. So I suggest this rhythm, it sounds better:
   
   Rhythm

   
2. 00:20:328 (1,2) - Same about this rhythm, it could be improved. Also, with the long slider 00:21:317 (3) you want to emphasize the piano, but it doesn't work, as the piano starts at 00:21:152 (before the slider). So, I suggest this rhythm:
   
   Rhythm

   
3. 01:03:185 (2,3) - You could make the first part of (3) parallel to (2), so that the sliders fit better together
4. 01:15:218 - Why this gap here? You could add a circle at 01:15:053

5. 00:09:778 (1) - It would have a cool effect, if you use Soft3 here, and add a whistle at the beginning and at the end
6. 00:24:284 (2) - Is that finish supposed to be there? Replace with a whistle
7. 00:46:701 (1) - Whistle? Because it is basically the same music as 00:45:383 (2)
8. 00:52:965 - I would not emphasize this slidertick, as it's no different sound from 00:52:223 or 00:52:471 and so on...
9. 01:15:712 (1) - Don't want to add finish here? :3
10. 01:20:987 (1) - Remove finish at the end? Because, basically the beat stops at 01:23:542, and this slider just ends on the white tick for simplicity. A whistle might fit, but not a finish

  fanzhen's part:

1. 00:49:009 (2,3,1) - Stack that correctly. Normally I don't care about these, but for triple-stacks it will mess them up if not properly stacked.

2. 00:04:009 (3) - Whistle at the head, because of loud instrument?
3. 00:06:647 (3) - ^
4. 00:07:965 (3,5) - ^ (on both circles)
5. 00:08:954 (2) - ^
6. 00:11:427 (1,2,3,4,5) - (1) and (4) should have the whistles, because they are the highest pitch.
7. 00:12:910 (4) - Whistle?
8. 00:24:943 (5) - ^
9. 00:26:756 (1) - ^

1. 00:03:844 (3) - Whistle at the tail?
2. 00:09:284 (4) - Whistle?
3. 00:49:668 (2,4) - Add claps on the heads? I think it would have a nice leading effect to the following stream

1. 00:50:657 (1,2) - any reason in partiqular for this antijump? kind of slowed me down
2. 00:51:976 (1,1,1,1,1,1) - I'd love to have louder finished especially for this part
3. 00:56:591 (3) - might stack this properly with 00:55:767 (1) -
4. 01:07:141 (3) - might stack this one correctly with the end of the slider
5. 01:15:053 (3,4) - might space this stream similar to 01:14:723 (2) - and 01:14:229 (1) -

General

1. Combo colors are not consistent throughout all diffs. Combo 1 in 'BASIC' differs from others.
2. Add a 2000 ms audio lead-in manually.
3. Check your storyboard folder, 'bright.jpg' and 'crepuscule.jpg' are unused. Remove them please.

EXPERT

1. Delete this redundant green line: 00:01:866.
2. 00:04:174 (4) - The clap on tail sounds quite noisy with two consecutive claps on one slider. And I don't see any boost in the prelude or similar sound in the music. Consider removing it. Same applies on 00:06:811 (5) and 00:08:295 (4) and 00:09:449 (5).
3. 00:10:438 (5,6,7,8,9) - The angle is too acute which makes the stream uncomfortable to click and read. Would this be better? Also, NC on (9) for indicating players there's a spacing change even the music itself doesn't provide an atmosphere for such change imo.
   
   SPOILER

   
4. 00:18:350 (4) - Delete this for consistency of following the 'ding' sounds instead of 'drum'. Same applies on 00:18:679 (6). If you feel deleting these two sounds hollow, replace 00:18:185 (3,5) by two 1/2 sliders instead coz slider tails do not sound as heavy as circles.
5. 00:22:471 (6) - NC this. I just can't figure out why you raise the DS on this circle provided that the ambiance doesn't alter much. I simply resist the mapping style of 'raising difficulty without listening to the rhythm'.
6. 00:24:943 (3) - Add a whistle like 00:27:580 (3).
7. 00:26:756 (1) - Whistle on tail like 00:24:119 (1).
8. 00:31:207 (2) - Why placing a 3/4 slider + circle here? The circle is following the drum alone. It's kinda inconsistent in the sense you change from following 'ding' to 'drum' unexpectedly.
9. 00:39:284 (2,3,4) - Make them as a straight line without using the grid snap.
10. 00:45:383 (1) - Finish on head too like 00:44:064 (1). Musically they are similar, though the volume can be reduced a bit.
11. 00:52:471 (1,1,1,1) - Doesn't really need NC imo, even though they are justly slightly 1/4 jumps. It's inconsistent with what you did on 00:46:701 (1,2,3) and 00:48:020 (1,2,3).
12. 00:58:075 (3,4) - Change this to a slider instead? 00:58:240 doesn't deserve a circle imo, the drum is too soft :3 It really plays better if you change it to a slider. Instead, you can replace 00:58:899 (2) with two circles, based on the two solid 'ding' sounds.
13. 01:04:504 (3,4) - Finish on these two, coz there's cymbal sound in the background.
14. 01:08:295 (2) - Move a bit upwards to avoid tail of (2) overlapping partially with (1).
15. 01:08:624 (3,4) - Same as 00:58:075 (3,4). I think what you are trying to do as a whole is to follow the instrument other than the drum. Consequently, 01:08:789 (4) shouldn't be treated as a stress. placing a slider there is far enough to catch the stress on 01:08:624.
16. To prevent same score for every player, add a spinner at the end till 01:26:262 for EVERY diff.

DIFFICULT

1. Delete this redundant green line: 00:01:866.
2. 00:04:174 (4) - Like EXPERT, also for tail of 00:06:647 (3) and 00:08:295 (5) (Also, why whistle?) and 00:09:449 (4).
3. Hitsound suggestions are basically the same with EXPERT.
4. 00:37:800 (2) - Kinda weird for the halt of (1). Second, you change to follow the drum on 00:37:800 which make me feel inconsistent to play. I can think of one alternative which can maintain your clap pattern. Make (1) as a 3/4 slider for the continuing 'ding' sound.
5. 01:13:569 (1) - CTRL+G to create a slightly symmetric pattern with 01:13:075 (1).

BASIC

1. 00:08:295 (3,5) - Improve this blanket a bit.
2. 00:32:526 (3) - Also, blanket issue. I have tried to adjust it for you. Feel free to take it.

3. 00:45:383 (2) - I wonder if the kink is being placed wrongly with the sound on 00:44:311. Instead, place the kink in the middle of the slider, same goes to 00:45:383 (2,1,2):
   
   SPOILER

   
4. 00:51:976 (1) - Missing a kink on 00:52:965. Just curving seems missing something imo. Btw, there're 4 red anchors in the middle, why not trying a symmetric slider?
5. 00:58:405 (3) - Curve more towards head of 00:59:229 (4) to improve the flow slightly.
6. 01:06:317 (3) - Make it like this by CTRL+H. It looks far more aesthetic.
   
   SPOILER

   
7. Hitsound --> EXPERT

BEGINNER

1. Why the circle density is even higher in the lowest difficulty? You need more long sliders to further reduce the difficulty, coz the setting imo is too low. OD and HP+1 would fit better the whole set.

1. 00:00:548 (1,2) - This part is useless in this diff, hard to feel rhytm. Suggesting delete this. D:
2. 00:14:064 (4) - Move to x:340|y:354 for better triangle with (2) and (3).
3. Why low OD and HP? +1 is better imo

1. 01:05:493 (2,3) - You should blanket it.

1. 00:39:943 (4,1) - Move (1) little right for nicer blanket, cuz this looks bad. :<
2. 01:07:635 (1,1) - Why NCs here? It is useless
3. 01:13:569 (1) - It is ruining the flow, Ctrl+G maybe? :3

• Beginner

1. 01:04:504 (3) - u can revise this slider by moving first red dot 304:280
2. 01:12:416 (4,3) - can be stacked
   
   Nothing else

• Basic

1. 00:55:767 (3) - instead of reversing this, 00:56:591 (4) - consider putting 1/1 slider here.
2. 01:08:295 (2) - consider centered-reddot

• Advanced

1. 00:34:833 (1) - for better shape, just few grid down plz
2. 00:37:965 (4,1) - completely stack

• Difficult
  

1. 00:08:460 (1,2) - misstacked a grid here
2. 01:07:635 (1,2,1) - i think nc is useless cuz hard diff can include triplets.
3. 01:23:624 (1,2,3,4,5) - i found here difficult but safe imo.

• Expert

1. 00:10:438 (5) - stream begins here so NC?
2. 00:17:690 (1) - overlap is someway weird. can u take these apart a bit?
3. 00:31:206 (2) - i understand ur thought to blanket this but i think putting that around 150:20 can have better flow.
4. 00:38:460 (5,5) - can u take this same-spaced?
