Please look over what I've said first before you start editing. Many of the points here will be relevant, especially if you don't want to remap over and over.
Insane
first off, you need custom combo colors.
second, you need to hitsound the map, and add in custom hitsounds as well. for example, 00:01:964 (7) and 00:01:964 (7) should be drum-type claps.
patterns seem kinda messy in general, you can try to change them by making more shapes/geometrical stuff/blankets and making more recognizable patterns in general. Check out
https://osu.ppy.sh/wiki/Mapping_Techniques for some inspiration. Study some recently ranked beatmaps as well.
You also need more consistent DS because everything is all over the place and it doesn't make sense. In general, notes that should be emphasized (finishes, important clap/whistle hits) will have higher DS following the previous object. Everything else would be the same DS.
I also noticed that there is an uneven balance between straight sliders and curve/sharp-angled sliders, so you might want to change that too.
00:34:232 - you need to make this spot the start of an object (for emphasis), since its the start of the chorus.
00:34:057 (4) and 00:07:197 (2) - like other modders noted, some sliders are too compact. In this case, they don't fit the music.
00:26:034 (4,5) - illogical DS, also happens here 00:55:001 (4,5,6)
00:51:095 (1) - looks messy because shape is not emphasized enough
00:56:953 - you will want a finish here
02:10:381 - ending the slider here makes no sense
02:04:523 (2,3,4) - these sliders feel very messy as well as detached from each other. You can try to make them look better by altering the shapes to blanket them. Also, the overlap on 3 and 4 does not look good.
02:26:358 - i recommend ending the spinner here (heavy drum-clap sound), then adding in a 5-note stream at 02:26:890 to lead back into the chorus. Also, you should map the end of the song.
Good luck!
