1. I know this might sound very nitpicky, but I think you should be saving as much space as possible in your maps if it can be done without loss. In your case, it's the background. If you really want to use this one, go ahead although it doesn't look well thanks to being so small. But don't resize a file that is 900x453 to 1920x1080, you're making an 80 KB file have 880 KB with even lower quality than the small one. Please, use the original or a completely different image. Don't ever upscale (except for maybe waifu2x action).
2. This is a bit similar to above, your soft-hitclap12 is ~900 ms long, while it doesn't need to. The volume it is used at is 50%, so essentially anything after ~300 ms won't be audible, not even talking about the fact that music is covering it too. Also, you by no means need to use 32bit wave files (and never should, you will probably not get in contact with a file that's recorded for that, ever, unless you buy it). It's not obligation, but I highly recommend you to use this instead, chopped down to 1/6th of the size.
3. The widescreen support could be consistent, but not really important, up to you.
4. I personally think all the difficulties should end at 03:32:785 - instead. 03:32:622 - sounds way too early, 03:32:948 - sounds way too late, but the arpeggio seems to really end at 03:32:785 - as there's no sound after that.
5. I'm pretty sure the offset is quite off. It probably should be about +10ms or so. You can easily notice that the hitsound at 01:23:655 - can be heard first and then the drum in the song, but other instruments can also be noticed quite easily.

1. 00:00:992 - You can't use inherited point on top of timing point with different settings. You can only change SV. Change the timing point's sampleset to Soft Custom 72. Could cause some issues (for example here, it's not clear which sampleset to use, although game picks one).
2. Does the increased tick rate serve any purpose? I don't see any need for that, it only increases the combo in my eyes. It could "fit" in the kiai, but you don't really hear it, in other parts, it sounds quite redundant. So as long as you don't use tick hitsounds or don't manipulate volume of them, I don't think this should be here.
3. 03:31:644 - Could have the default soft hitsounds, using a clap and the whistle that it already has. You can notice the song has a very noticeable clap in it, so I thought it might be worth emphasizing the only one that seems to be here, to make it a bit more interesting. Applies to other difficulties too.

1. Some objects could avoid touching the HP bar quite easily, up to you, minor issue. 00:22:513 (1) - 00:28:383 (1) - 01:19:252 (1) -

1. 03:31:644 (4) - Could easily avoid touching the HP bar, again, completely up to you.
2. 01:44:035 (4) - A clap is definitely missing based on your hitsounding structure and how you follow song by hitsounds.
3. 01:45:502 - Same as above.
4. 03:21:861 - Same as above.
5. 03:23:328 - Same as above.
6. 03:30:665 - Same as above.
7. 03:30:991 - Same as above.
8. 00:05:883 - Missing whistle (you have it in other difficulties)
9. I think the map is missing many clap hitsounds (not like you just forgot them as the above listed, but that it could just have more). I know you like to follow the accordion, but maybe at least places like 01:24:470 - could have a tiny snare on the slider ticks? It's up to you, I just felt it sounded a bit empty hitsound-wise when following the accordion.

1. 00:05:883 - Missing whistle
2. I would suggest the same thing with slider ticks as on normal. Except in this case, there are virtually no clap hitsounds, which feels even more weird. It wouldn't be an issue because the map simply doesn't allow you to do that, but at least the ticks could improve this situation. (if you make them, they don't have to be loud, and no, they won't confuse players if they don't stand out too much)

   I think I understand the issue here - the current BG is indeed based on the image's original resolution (3100 x 1560) which actually was being downscaled to 1920 x 1080. It's just when I did this in Photoshop seems like I accidentally set the .jpg quality to 12 (Maximum), hence the large file size :3
   
   Things should be good now, though.

   Eh, the link's broken when I tried to open it unfortunately o.o...
   
   I've tried doing this manually in Audacity but oddly enough the file size didn't reduce (312 KB -> 312 KB) even after I trimmed the ending part, so I'll be leaving this as is~

3. The widescreen support could be consistent, but not really important, up to you. Yeah, forgot to remove the Widescreen Support on Easy
4.

Decided to end this on the next white tick instead following the current Easy diff's end

Hmm, yes, there are many faint snares (even outside the kiai, on 00:58:393 - for example) in which the Tick Rate 2 would blend nicely into~
3. 03:31:644 - Could have the default soft hitsounds, using a clap and the whistle that it already has. You can notice the song has a very noticeable clap in it, so I thought it might be worth emphasizing the only one that seems to be here, to make it a bit more interesting. Applies to other difficulties too. Used Sampleset : Drum + Addition : Soft instead, the default Clap just feels to strong here in my opinion...

1. Some objects could avoid touching the HP bar quite easily, up to you, minor issue. 00:22:513 (1) - 00:28:383 (1) - 01:19:252 (1) - Moved the last two lower, should be better now (I don't know how to move the 1st one from its current position, though xD)

[Normal]

1. 03:31:644 (4) - Could easily avoid touching the HP bar, again, completely up to you. Redesigned this slider in order to make it end in the next white tick, should be fine now
2. 01:44:035 (4) - A clap is definitely missing based on your hitsounding structure and how you follow song by hitsounds. Fixed
3. 01:45:502 - Same as above. This is intentional actually
4. 03:21:861 - Same as above. Fixed
5. 03:23:328 - Same as above. This one's also intentional
6. 03:30:665 - Same as above.
7. 03:30:991 - Same as above. Changed into clap + Sampleset : Normal for these two
   
   Regarding the "claps", the idea here is actually not to over-saturate the mentioned parts with claps as the mapping is very much following the accordion (while the accordion sounds fall on the white tick and many of the claps actually fall on the red tick). This is why on some parts that you mentioned, such as 01:45:502 -, a Sampleset : Normal has been positioned there instead of a Clap as using Clap there would feel out of place due to there are no red tick claps nearby :3
   
   .
8. 00:05:883 - Missing whistle (you have it in other difficulties) Fixed
9. I think the map is missing many clap hitsounds (not like you just forgot them as the above listed, but that it could just have more).

It's up to you, I just felt it sounded a bit empty hitsound-wise when following the accordion. I think I'll leave this as is though, I'm not really a fan of slidertick hitsounds o.o

(if you make them, they don't have to be loud, and no, they won't confuse players if they don't stand out too much) Yeah, once again due to the nature of the percussion here basically the 1/1 and 2/1 rhythm don't fall at any clap at all except for one object. I guess I'll leave this as is as well though, I think the current hitsounding works fine as is and that adding claps in the sliderticks wouldn't really fit the current rhythm >_<

Generally a very nice mapset, would like to see this ranked. Also, welcome back! Thank you~

I've tried doing this manually in Audacity but oddly enough the file size didn't reduce (312 KB -> 312 KB) even after I trimmed the ending part, so I'll be leaving this as is~

Oops, not sure why the link got corrupted. This should work though.

1. 00:17:958 (4) - Jumps are okay, but this one is a bit forced for me. Everything flows better if you add Ctrl+G here and jump to 00:18:284 (5) - is kept.
   It's a personal suggestion, but I think it's a good one.
2. 00:24:317 (8) - The pattern looks a bit unclean because you forced the stack here. Spacing between notes is broken and I really felt like it was a straight line and suddenly it wasn't. Try to move (1) further or just do something else.
3. 03:27:415 (7) - Jump pattern was cool until I've seen this. They are not really touching, but it doesn't look clean at least for me, try to fix spacing here.

1. Looks cool.

1. 00:09:480 (2) - Actually this note should be up due to the flow movement that sliders have.

1. Nothing to say here neither.
