General
Your first object is at 00:00:149 - you need at least 2000ms before the first object starts in the map. Go to .osu in Notepad and add 2000 to AudioLeadIn for all difficulties
Normal
00:04:669 (4,1) - you have to keep the spacing constant with all the notes
00:11:244 (6,1) - ^
00:17:820 (4,1,2,3,4,5) - ^
01:16:381 (3,4,5) - spacing needs to be constant
01:18:025 (1,1,2) - ^
01:32:614 (1) - don't use another new combo here
01:45:354 onwards - you changed spacing again, you need to keep spacing the same throughout the whole map
01:56:861 (1,1) - time between these objects is too short, you need more time before the next object after a spinner, if not this is unrankable
I really would not recommend using so many repeat sliders with more than 1 repeat, because this can cause confusion to players who aren't familiar with the song, and won't expect this, especially in a Normal. I don't think this would be allowed to be there unless really obvious for ranking.
Spacing is the biggest issue here, you have to keep it constant. I wouldn't recommend the slider velocity changes as well, because that affects the spacing
Hard
Your combo lack the sense of consistency, they look messy, make them more consistent and look like they make more sense.
00:06:724 (3) - new combo here and not 00:07:135 (1) according to your current combo pattern
00:13:300 (2) - ^
00:40:629 (1,2,3) - make it more even
00:53:985 (2,3) - blanket them
01:02:615 - why empty, unlike previously, add a note
01:05:903^
01:07:136 (2,3) - blanket them
01:40:423 (1,1) - no reason to have a new combo
02:13:734 - insert a break here, this is too long a gap for draining time
02:15:355 (1,2,3,1,2,3,1,2,3,4,5,6,7,1,1,2,1,2,3,1,2,3,4,1,2,3,4,1,2,3,1) - combos aren't consistent, especially here, rework it
02:28:094 (2,4) - stack the ends at least if you want this pattern
02:30:560 (5,1) - they can blanket
03:00:971 (1,1) - doesn't require so many new combos
03:06:520 (1,1) - just 1 single combo, not separate
03:12:478 (5,7) - stack properly
03:13:300 (7,8,1) - this doesn't flow well, especially to 03:13:916 (8)
Object placement needs to look more organised and well-positioned so that it can flow well. Combos need to be better, it's not organised and not well used
Insane
02:07:546 (7,8) - blanket properly
02:09:190 (4,6) - stack properly
02:19:670 (3,1) - this anti-jump is too weird, it doesn't fit. Use normal spacing
02:24:807 (4) - New combo should be on big white ticks like these, where the new phrase in the music starts
03:27:889 (1) - unexpected as you weren't using this rhythm at all up until this point of time
03:31:382 (3,5,7) - you can space them apart equally
Combos are confusing and inconsistent as well. Placement can be improved to help flow, most of the map is just circle jumps, more impact can be made by using more variety of intensity for different parts of the song. I would disagree with the offbeat starting sliders but I will leave it to more modders to see if it affects their gameplay too.
Good Luck in improving and finishing this. Normal is too high a star rating to be the lowest difficulty, you will have to have an Easy.
