hi
These are all suggestions,
feel free to use any~
[General]
I know i'm beating a dead horse here, but a background would be nice hehe. 
Have a scan through your difficulties for unused green lines that should be removed as it appears there's a good amount of them.[Easy]
00:06:148 (1,2) - These two can fit together more nicely. If you shift up (2) a bit, move the red anchor a bit further up and adjust the curve objects would look neater:
00:41:120 - Beginners are going to feel the need to click something here on their first play because the vocal is so prominent, and they may feel the need to rush their cursor over to 00:41:634 (1) and accidentally hit it extremely early. Why not just add a 1/1 slider here. It would fit in nicely with the current formation too.
00:52:091 (3) - It would look neater if you could center this slider between 00:50:205 (1,2) so the head is nicely blanketed and then rotate it slightly to correct the distance.
01:16:091 (1,3) - Not stacked perfectly.
01:18:834 (1) - Spacing inconsistency here.
01:19:863 (2) - Missing a clap here?
01:20:205 (3) - Add a finish on the head since you had one here for Normal.
01:22:605 (2,3) - Something like this would be divine since the tail of 01:21:577 (1) isn't fully overlapping the sliderbody, plus a triangle formation between the tail of (1), (2), and head of (3) would feel more organized:
In general I feel the rhythm you're using for this difficulty is quite challenging for an Easy in a 4-diff mapset but that's just my preference.
[Normal]
00:41:120 - Similar suggestion as Easy. I get that you like sticking to the instruments but sometimes skipping out on strong vocals (especially on for easier diffs) can throw novice players off guard. Consider changing 00:41:291 (5) to a reverse slider starting on 00:41:120 for this exact reason as well:

By mixing vocals and music you will make the diff a bit more interesting enjoyable for players, try to do something similar more often! 
00:44:548 (1) - Huge spacing inconsistency here is going to make players hit 00:45:405 (2) way too early.
00:47:291 (1) - And again here, will create the same problem
00:52:777 (1,2) - Try to get these to reflect perfectly along the y-axis, would look cleaner. If you CTRL-H either of two you can see what I mean.
00:55:177 (3,2) - These would be good perfectly centered for a symmetrical image if you followed the previous suggestion. Make sure to adjust the distance to 00:55:520 (1) if you do.
00:59:291 (2,4) - Stack on the tail properly, it's actually pretty noticeable.
01:08:377 (2,3) - This doesn't look very nice, maybe if it was more overlapped.. but the slight touching isn't very aesthetically pleasing.
01:12:663 (4) - Hmm, was really expecting to click something here. A note here would fit nicely because of the drum hit in the music. The 3/2 gap is also very unexpected since we haven't seen one since very early on in the difficulty.
01:18:834 (1) - From this point until 01:22:948 (3) you clap pattern is discontinued. Not sure if this was intentional because some appear between these times on Easy, so I would add claps here where appropriate.
01:26:034 (1) - Makes more sense to me to use a clap on the reverse than a whistle.
I like CS4 normals! This diff is awesome.
[Hard]
00:17:120 (1) - This slider looks a bit distorted since the top and bottom portions are angled slightly differently. Try and get both parts to line up parallel.
00:23:977 (1) - End slider-point to x:407 y:20 for a better blanket.
00:28:605 (3) - Whistle sounds better on the end of this slider imo. Also because there's one here for both Normal and Insane.
00:38:891 (1) - This is really the only part of this map that doesn't flow well. Because of the massive spacing increase, the movement to this slider is very reactive and not so much instinctive. I agree with the use of a jump here, but please try to tone down the spacing here because it wasn't comfortable to play.
01:02:377 (2) - NC for the kiai start.
Looks good flows well, not too much to say here. I would have a scan through the diff for objects that aren't nazi stacked perfectly because there are several.
[Laurier's Insane]
00:04:091 (1,2) - I think this jump would feel more natural if you used a gradual spacing increase in the previous combo to build up to it. For instance having 00:03:577 (2) placed at x:176 y:74 and 00:03:920 (4) at x:289 y:52. Try it out.
00:21:063 (1,2) - Shorten this reverse to end on the red tick. I would imagine that a majority of players are going to release this early to hit 00:22:263 (2) even though the sound ends on the blue. If that doesn't really fit for you, it would be nice to try and make it easier to read. To be honest I would just add a spinner here to get some score variation for your difficulty since there are none and give the pros more incentive to get on the leader-boards.
00:58:777 (4,5) - The flow here feels strange as your style appears to use a lot of acute-angled jumps and that was not the case here. Players are going to instinctively feel the need to sharply change direction here and I think you should change this to accommodate for that. Maybe try doing Ctrl-J and stacking this on 00:58:434 (2) and see how that feels (or try something similar).
01:23:805 (2,3,4,1) - Maybe you can try to organize this into more of a cleaner box/diamond formation?
01:27:748 (5) - Would be nice if this was centered perfectly.
Good stuff.
Great mapset mochi! Your maps are always fun to mod and the songs are always lovely (the video is pretty funny too). Also I saw that you updated this while I was modding, hopefully nothing has changed.
Best of luck~
