1. 00:00:221 (1) - Hmm, why don't you start your claps here (as galvenize did in his difficulty)? The claps from the song already started even from the beginning (:
2. 00:00:869 (2) - (optional) As this is your easiest diff (which will be played by beginners), I think it's better to simplify the rhythm here to help beginners, for example you can make 00:00:221 (1) as a 2/1 slider followed by a note 1/1 after
3. 00:05:085 (x) - The beat you're skipping here is very distinctive, it's best to map this beat as well (maybe you can arrange like this: )
   
   SPOILER

   
4. 00:09:302 (5) - It will be much better to follow the synth here (by using 3/2 repeat slider) rather than forcing with the bass, about the placement you don't have to worry because this slider could be easily moved to x:44 y:300 without ruining the flow~
5. 00:10:599 (1) afterwards - Hmm, why don't you start your 1/1 clapping here? Clapping every 2/1 is usable, yes, but it doesn't sound that good considering you only have a little amount of objects here (on harder diffs, it will sound better though, but not on LIGHT)
6. 00:14:166 (x) - Add a note here? From what I've seen, 2/1 delay between notes is easier to read for beginners rather than 3/1 delay (plus, this is a good place for a clap as well)
7. 00:15:464 (2,1) - (optional) Structure around here could be better imo, for example:
   
   SPOILER

   
8. 00:20:977 (x) - This is an excellent place for finish hitsound - I strongly suggest to add a note here with finish and move the spinner 1/4 later
9. 00:28:112 (5,6) - Uh... unstack this if possible (you can move (5) to x:328 y:160) because this stack will be overlapped by (4) in play mode - if you don't want to fix this, at least move them one grid down (:
10. 00:30:058 (2,3) - This rhythm could be greatly improved by using 1/2 short sliders on 00:30:058 and 00:30:545
11. 00:33:950 (1,2) - Try to make them not overlapping each other? Simple arrangement like this will do:
    
    SPOILER

    
12. 00:37:518 (2) - Move this one grid down to follow 00:36:220 (6)'s placement, but this is barely noticeable
13. 00:56:977 (x) - (optional) Considering the song will go intense with the bass after this, a note with clap here would be good~
14. 01:04:112 (4) - Move this few grids up/down, so (3,4,5) will create an arc, thus creating a better flow?
15. 01:07:031 (4,5) - Again, due to stacking's nature, I suggest to unstack these or at least stack (5) above (1) instead to avoid (4) overlapping your next slider
16. 01:10:274 (1) - The fact that this slider's end got overlapped by 01:08:977 (3) will make this slider look weird in play mode, maybe you can try this to avoid overlap:
    
    SPOILER

    
17. 01:12:220 (4) - Minor stuff, but move the midpoint one grid down to encircle (3) better
18. 01:18:058 (1,2,3) - Hmm, I get what pattern you're trying to create here, but I think it will be better if you curve (1) this way so it will perfectly encircle (3)'s start:
    
    SPOILER

    
19. 01:41:410 (3,4,5) - (optional) Stacking three notes in a row with a huge delay like this will create a weird stack, it's not that hard anyway to unstack this while keeping your symmetry ><

1. 00:00:221 (1) - Why no finish hitsound here (as you did in [LIGHT]) o.o
2. 00:03:464 (x) - Add a note here? The synth continues here, also adding a circle here will create a more intuitive rhythm
3. 00:08:004 (6,7) - (optional) Try to unstack (7) and create a diamond pattern here? Stack here is fine, but it will ruin your spacing from (5) to (6)
4. 00:10:599 (1) - I like your idea to use 2.0x spacing on your previous (1,2,3) here, but continuing it on this slider will create clustering. A jump like this will play better imo:
   
   SPOILER

   
5. 00:10:923 (2,5,...) - Again about the clapping here, claps following the synths are basically usable but I prefer to let the clapping consistent every 1/1
6. 00:14:977 (4) - Move this one grid down? This is a minor stuff indeed, but would be nice to be done because currently your (4) almost touches (3) and doing this will avoid so
7. 00:20:491 (4) - Why don't you continue to encircle (3) here, like below? The square formation is nice, but it would be much better if this isn't curved overlapping (1)'s curve:
   
   SPOILER

   
8. 00:20:977 (x) - Same as [LIGHT] here - add a circle with finish and start the spinner 1/4 after?
9. 00:24:058 (1) - Hmm, don't put this circle in the center - the 3/2 delay after the spinner is basically quite hard to read (especially on Hidden), and it will be even harder because the spinner's hitburst will cover this (moving it up/down a bit will be better)
10. 00:28:923 (2,4) - (optional) Would be nice if these two is curved into an opposite direction (example: curving (2) upward and (4) downward) to create an antagonistic effect here, they will look fancier
11. 00:32:653 (7,8,9,10) - This diamond pattern is uneven on (10), is it intentional?
12. 00:34:923 (6) - (optional) imo it will be good to create a sparser jump here with this slider encircling (2)'s start like below:
    
    SPOILER

    
13. 00:39:626 (4) - Do you really need the whistle here? I think it's better to remove it, as it will emphasize your next whistles
14. 00:41:410 (10) - CTRL+R this for a good jump? xD
15. 00:46:923 (1,2,3,4,5,6,7,...) - (optional) Again, with some CTRL+R, you can alter their order to create a jumpy formation:
    
    SPOILER

    
16. 00:50:815 (5) - Not perfectly stacked to (1), is this intentional?
17. 00:58:599 (1,2,3,4,5,6,7,8) - (optional) Arrange these eight circles in a wave formation instead of an arc? Will be much better before the spinner imo
18. 01:01:761 (1,2,3,4,5) - Definitely you're stacking this too much here, I think it's best to alter (1,2,3) as a repeating slider to avoid overstack like this and give more variation to this part
19. 01:10:437 (3) - As your next (5) is curved already, it feels kinda weird having this uncurved (you can just simply curve this upward, it will do good here)
20. 01:12:869 (1,2,3) - They're not perfectly stacked, but it's barely noticeable
21. 01:16:112 (6) - (optional) To give more variation to this part, how about facing this slider to the right instead of left? Don't worry - your approach rate is fast enough here, overlap won't happen[u]
22. 01:33:193 (8,4) - They're not perfectly stacked as well, but [u]this one is quite easy to notice - won't be hard to fix, though~
23. 01:43:356 (x) - A note with whistle is supposed to be here - I suggest to add it, and move the spinner 1/4 later (yes, in the rules spinner's minimum limit is 1000 now, and this spinner is still easy to 300 although it's cut short by 1/4)

1. 00:02:645 (2) - Minor stuff, but move both midpoints (the red and bezier one) 1 grid left to encircle (3) better
2. 00:04:104 (1) - CTRL+R this? I like the jump from (5) to (1) here :3
3. 00:05:240 (3) - (optional) Perhaps add a red waypoint somewhere here? Plays fancier imo:
   
   SPOILER

   
4. 00:08:321 (6,7,8,9,10) - Something bugs my mind about this fan pattern... I personally feel (10)'s endpoint should be dragged upward more, but probably that's just my feeling
5. 00:10:591 (1,2) - Perhaps try to curve (1) more or curve (2) less to create equality here?
6. 00:14:158 (6,1) - Not perfectly stacked, but this would be hard to notice (especially for players without transparent hitburst)
7. 00:16:104 (2,3) - (optional) I think it will be good to combine these two as a slider which starts on your current (3), the jump here will play good imo
8. 00:20:969 (1) - Add finish here? I like how the finish splashes here~
9. 00:21:618 (6) - Hmm, I personally feel the whistle here isn't required, it can emphasize your next whistle in (7) if removed imo
10. 00:33:780 (4) - Is it intentional to put this further compared to (1,2,3)? I know they aren't hard to catch, but still...
11. 00:35:726 (3) - (optional) Dunno why, I just feel better if the notes are placed like below so (1,2,3)'s jump will look less random:
    
    SPOILER

    
12. 00:39:456 (4) - Hmm, why the clapping pattern stops here? Feels kinda weird having it suddenly stopping (as the claps from the music still continues here) o.o
13. 00:52:429 (2) - (optional) Make this as a jump also? (in this blue combo, everything is a jump/stack except this one)
14. 00:55:672 (1) - Why don't you curve this encircle (3) instead? I like the angle the created with your next slider as well:
    
    SPOILER

    
15. 01:01:672 (1,2,3) - Try to create a manual stacking or a moving stream from the bottom-right here? Due to stacking's nature, in play mode (1) will be overlapped by (14)
16. 01:06:212 (6) - I'd rather move this ~2-3 grids up to keep the spacing consistent with your previous (1,2), but it's fine as is as well
17. 01:07:672 (6) - (optional) New combo here to break your long combo chain?
18. 01:12:537 (1,2) - These two isn't placed perfectly below the previous (1,2), is it intentional? (if not, I think it's better to move them more to the right to emphasize the jump here)
19. 01:20:807 (2,3) - A jump here is good, but I wonder why don't you add a triple here as well (as you previously did before)? Sounds kinda weird without a triple here imo...
20. 01:41:834 (1,2,3,4,5,6,7) - I personally dislike the overstack on the end... A moving stream like this would be great, though:
    
    SPOILER

    

1. fine

1. 00:27:302 (4) - stack with next note?
2. 01:05:085 (1,2) - I think stacking them on 3's head is better.. = =

1. 00:36:537 (1) - stack with (2)..? back jump doesn't fit here I think...
2. 00:41:564 (2) - move to (164,44) ? position with slider is better in this way.
3. 00:43:456 (3) - why is it not stacked..
4. 00:46:267 (4,5,6) - ._.
5. 00:51:618 (2) - move to (392,180) ? I think it plays better when it's on the right
