Normal

00:10:855(3) - i would just make the previous slide a repeat slider. although it's the right spacing, something just looks wrong, idk. I like the hitcircle here, I think I’m gonna keep it.
00:13:962(5) - end slider here Fixed.
00:17:069 and 00:17:391(x,x) - these two spots needs notes imo. Fixed.

01:02:712(x) - add note? Fixed.
01:09:784(x) - add note with claop Fixed.
01:22:641(1) - may be better just to move this a little further away Fixed.
01:42:998(4) - this note belongs at 01:43:105, and also this will be a little hard to read, so i would also recommend spacing it out Fixed.
01:48:784(spinner) - silence the spinner I have to look into how to do this.
Hard
00:07:105(5) - end slider here. Fixed.
00:08:498-00:17:712 - i would follow the music more in places like the one i just mentioned. It may sound better. The way it is now is perfectly fine tho I guess I’ll keep if you think it’s okay.
00:23:498(2) – clap Fixed.
00:40:212(5,6) - i would delete combo 5 and move combo 6 a red tick back. (then fix spacing if needed) Fixed.
00:57:141(1) - i would replace this slider with a note at 00:57:355 Fixed.

00:58:212(4,5) - sounds weird. try something like this: Fixed
01:03:998(x) - add note Fixed.
01:11:927(spinner) - start spinner here Fixed.
01:16:212(4,5,6,7,8) - i would use the same pattern as combos 1,2,3 (as in i think it would be better if they sounded the same. you don't have to make them all sliders) it doesn't really matter tho. I think I’ll keep it for now.
01:47:069(spinner) - end spinner here? and also silence the spinner Fixed.
01:55:641(8) - make more symmetrical? xD I tried to make it more symmetrical
02:16:427(8) - start repeat slider here and end at 02:16:641 and fix spacing Fixed.
02:18:569(6) - a little awkward, since i really want to play a note at 02:18:784 Fixed.

[Easy]
0:05:927 (1) - move it by one grid to the left Fixed.

1:25:213 (1) - start that spinner a bit earlier, like 1/2? I think it’s okay there.
2:00:141 (1,1,1) - yeah, combos. I like the new combos, sorry!
2:11:070 (1) - delete this note, that way this difficulty will be more consistent with the others. also, if you're going to do this, delete that timing section at 2:10:212. Fixed.
2:14:499 (5) - move it by one grid to the right (despite distance snap, it just plays a lot better). also, this slider kinda feels like it should be 1/2 longer...click. Fixed.

0:24:784 (1,1,1,1) - once again, those combos I like the new combos, sorry!

0:53:927 (2) - move it onto x: 234 y: 256 Fixed.
1:05:926 (1,1,1,1) - pretty much like before I like the new combos, sorry!

0:42:355 (3) - move it onto x: 153 y:248, to keep the perfect flow. Fixed.
1:03:141 (4) - slightly inconsistent spacing I think I fixed it.
1:05:926 (1,2,1,2,1,2,1,2) - pretty much like before. I like the new combos, sorry!
1:10:855 (2) - move it like this so it plays a lot better, i suppose. Fixed
1:11:498 (5) - slightly inconsistent spacing Fixed.

1:41:498 (1,2) - swap new combos Fixed.
2:10:212 (x), 2:11:927 (x) - those timing sections are innecessary Okay.
2:14:712 (4) - start it 1/4 later I can’t figure out where, it’s okay where it is I think.

2:54:462 (1,3) - swap new combos Fixed.
2:56:927 (1) - start that spinner a bit earlier, like 1/2? Fixed.
also, if you feel like there's a dynamic part of the song, don't hesitate to add some streams into the map! those complicated kickslider patterns are unfun to play and kinda destroy the flow of the music. i've expected few sweet, straight sliders.

Resnap All notes Fixed.
02:25:641 - kiai time start Fixed for all difficulties.

[Normal]
00:20:927 (1) - remove new combo Fixed.
01:02:712 (1) - ^ After having done it, please repair spacing. Fixed.
01:23:498 (1,1) - ^ Couldn’t find anything wrong with the spacing? Tried playing around with it.
02:25:641 - same as Easy Fixed.
02:29:069 (2) - just stack with here 02:27:355 (4) – Fixed.

[Hard]
AR7 Fixed.
00:31:212 (1) - spin start 00:30:784 – Fixed.
00:40:427 (6) - start here 00:40:212 - Fixed.
02:18:784 - add note (new combo) Fixed.
02:18:998 - ^ Fixed.
02:25:641 - same as others diff. Fixed.
02:35:284 (7) - far. Fixed.
02:52:748 (8) - new combo Fixed.

[General]
- The hitsounds seem a tiny bit loud to me, maybe reduce by 5 or 10 percent. I reduced it to 85% for all difficulties.

[Easy]
02:27:784 (5) - Put a New Combo here. Done.

[Hard]
00:37:212 (1) - This spinner is rankable but still really short and sort of not necessary. I would advise changing it to a slider. I like the spinner, if it’s rankable, I think I’m going to keep it.
00:47:069 - Drag the first break to this point. Done.
02:10:212 - Remove the unused inheriting section. Done.
02:27:141 (1,2,3,4,5) - This is pretty confusing. At least adjust (4) and (5) a little so it's more readable. Fixed.

[Overall]
I'd force your skin since this really is a well made storyboard/skin for the mapset. (Some hitsounds conflict with my personal favorite the taiko skin) You can do that by forcing what you have in your sprite library as a skin itself. Hope that's not too confusing. I kinda like having it as a storyboard, so I think I’m gonna keep it. Thanks for the suggestion though. ^^

4 AR/OD?

Just a tad hard for a beginning diff. Only suggesting 3 AR/OD but it's up to you. Changed it to 3 AR.

[Normal]
Excellent stuff here.

Enjoyed this diff the most Thanks!

[Hard]
WE GOT THAT BOOM AND CLAP FOR HITSOUNDS BUT I FOUND NOTHING HERE Haha, since I lowered it to 85% there should be less BOOM CLAP now xD

[Easy]
This is an odd way to lead the player in to the next section. Use the red ticks. I would fix this but I’m not sure what section you were talking about. If you get a chance, could you let me know what time this section started?

[Normal]
00:05:926 (1,2,3,1,2) - A bit of a boring way to start the map. Use the blue ticks? Remapped to make less boring.
02:35:927 (1,2,3) - Use some blue ticks? Remapped with blue ticks.
02:51:998 (2,3,4) - See above. Remapped with a blue tick.

[Hard]
00:43:212 (4) - Clap at the beginning. Fixed.
02:14:712 (4) - Remap this section a bit so there's a hit on this blue tick? Remapped with blue ticks.
02:36:569 (1,2,3,4,5) - Remap this to use some blue ticks where the melody does? Remapped with blue ticks.
02:52:784 (1) - Fix this; nothing should be off the 1/4 ticks. Fixed.

[Overall]
I second the "turn the hitsound volume down a bit" comment. The hitsound volume has been turned down.
