General
Your first object starts at 00:01:485 - you need a minimum of 2000ms before the start of the first objects, so you should add at least 600 to the AudioLeadIn in Notepad for the .osu for both difficulties
Normal
Make sure you got check the whole difficulty for inconsistencies in the spacing, I might have missed out some but I will point out some
Your use of combos are very inconsistent, try to use it consistently after a phrase a verse or a set number of beats
00:01:485 (1,1,2,3,1,2,3,4,1,2) - sounds very empty without hitsounds
00:05:285 (4) - curve this slider less
00:07:285 (2) - sounds more natural to end at 00:07:685 - you don't have to end it at 00:08:085 it is fine to leave that part empty
00:11:285 (1) - the slider end could use cymbal hitsounds, namely either normal or soft default finish
00:14:085 (5) - ^
00:17:885 (1,2,3,4,5,1,2,3) - I find this pattern very angular, and doesn't really play too well
00:27:685 (2) - default finish on start of slider
00:33:685 (1) - default finish on end of slider and so on so forth, for similar parts in the music
00:36:485 (2,3,1) - spacing error
00:37:285 (1,2) - use the same shape
00:42:885 (4,1) - could have blanket
00:43:685 (1,2,1) - the flow for this isn't really there, 00:44:485 (2) moves in a very weird direction compared to the rest
01:01:085 (1,2,3) - messy positioning, maybe avoid overlapping them
01:04:285 (2,4) - doesn't look good with overlap
01:11:885 (1,2) - spacing error
01:13:885 (1,2) - 01:14:485 (2) is too high up
01:17:085 (2,1) - avoid this overlap
01:18:885 (1,2) - avoid looking like they will touch each other
01:23:085 (3,4) - I wouldn't recommend stacking these 2, it isn't really good for playing, or for the players, especially in this Normal
01:43:685 (2,3) - not gonna place them on the same level?
01:49:285 (6) - you suddenly changed the combo sequence again to last 2 4 beat bars now. Even so, this is wrong, there should be a new combo here instead of 01:50:085 (1) for the new phrase of vocals start here
01:53:285 (2,3) - this placement can confuse people, they may think there is an additional repeat in the slider, it should be repositioned so that confusion won't occur. Basically, don't let them touch each other
01:55:685 (1,2) - I don't think a stack fits
01:58:885 (2) - NC is here not before this
02:00:485 (1,2,1,2,3,1,2,3,4,1) - another example of inconsistent combos used, please make it more systematic
02:02:885 (3) - don't use more than 1 repeat, over here it is confusing and it won't be good for the Normal
02:17:085 (3) - this sounds off because the beat at 02:16:885 is much stronger but it's empty
02:17:085 (3,4,1) - clogged up, doesn't look tidy and looks too compact
02:19:485 (3) - further down, it's too close to 02:18:085 (1)
02:23:885 (1,2,3) - unstack, it would be better
02:29:885 (3,1) - not even stacking on each other
02:33:685 (1,2) - blanket
02:59:485 (4,6) - avoid such overlaps, placement can be better, it can be placed elsewhere
03:05:285 (3) - don't use more than 1 repeat, it's too confusing
03:06:285 (1,2,3) - stacking doesn't fit, and won't be good here in Normal
03:06:285 (1,2,3,2) - not good overlapping
03:12:285 (2,4) - don't overlap
03:13:685 (4) - bad slider, it ends on 03:14:085 which is the start of a new phrase, which should have something start here instead of ending, and be a new combo
03:24:285 (5) - shouldn't be stacked with 03:23:885 (3,4)
03:30:085 (1,2,1,2) - one thing about this is that they don't look like they come on after another, they don't look like the compliment each other. They look like random curves all placed together just to form a rhythm. They should look more presentable and look like the relate to each other. One way is to use similar shapes by copying the shape of a previous slider and using it for the next one but by changing it's angle, direction, etc.
03:32:485 (3,3) - don't use more than 1 repeat, it's not obvious enough in the song
03:38:085 (1) - ends on nothing. End the spinner at 03:44:285
Normal uses very start-stop rhythms, focusing too much on the vocals, hence ending very weirdly in many cases. try using more simplistic rhythms, and longer sliders to join up phrases. The placements look pretty messy and not much uniform pattern can be seen. A lot of unnecessary overlaps can also be found and movement is limited and flow cut at times. There really is a feel of a lack of hitsounds here. Don't just use the custom hitsounds, they limit you a lot in what they can provide in terms of sounds. Use the default hitsounds as well to make it sounds better, especially finishes and soft whistles, they can help this map a lot. Combo aren't done consistently and is in a mess. Use a more structured way of deducing when to use a new combo. I suggested earlier already to systematically use whenever there's a new phrase or set of beats
Hard
Very ugly inconsistency in the spacing. Please do something about that. Still lacking a lot in terms of hitsounds. Movement is too angular and straight, flow is hampered
00:03:485 (1,2,3,4) - this change in spacing is rather obvious and glaring, it doesn't look good
00:06:085 (1,2,3,4,5,6) - very angular flow, not good, and nor does it look fantastic
00:22:485 (5,6,7,8,9,1,2) - ever changing spacing looks horrible, please do something about it, use more proper spacing and change only when needed
00:24:285 (1,2) - would look much better as a blanket
00:24:285 (1,4) - don't even stack properly at the moment as well
00:25:885 (5,1) - really ugly spacing, they touch each other. 00:26:085 (1) is also blocked a lot by the previous slider, this makes it harder to read, as well as look messy and ugly
00:27:685 (2) - this should be where NC should start. Be mindful of your NC and use it properly
00:29:885 (3,4) - overlaps like these take away presentation points and look ugly
00:30:085 (4,1,2) - no consistency in spacing
00:34:085 (2) - Big downbeat is here, why isn't the new combo here
00:37:285 (1) - the curve is too sharp
00:38:085 (2,3) - don't place 00:38:685 (3) behind the end of the slider, flow is bad
00:39:485 (5,1) - no direct stacking? this looks bad
00:45:685 (6,7,8,9) - the change in spacing again doesn't make sense
00:51:885 (1,2,3) - ^
00:54:685 (1,2) - spacing, this is too small
00:55:085 (2,3,4,1,2,3) - consistent spacing please
00:57:685 (4,1) - at least stack directly on each other
01:04:885 (2,3,4,5,1) - anti-jump not suited for this part
01:06:885 (2,3,4) - this kind of pattern positioning is bad for flow, it's too rigid and angular
01:12:485 (4) - new phrase starts here, where is the new combo
01:17:085 (2) - ^
01:18:885 (2) - ^ and so on so forth
01:20:285 (5) - ^ and so on so forth
Stopping after the first break, there is still a lot to be done. New combos need to be worked to be more consistent and make more sense. The flow has to be there, it's too rigid right now. I feel no sense in the power of the song, in the chorus, no impact. Spacing is too irregular, even for a Hard, it needs to make more sense to be more comprehensive. Watch out for blankets, for stacks as usual, and be mindful of previous patterns, lest you overlap and make it look ugly. More hitsounds to make it more impactful, default hitsounds help with that a lot.
Still a long way to go, good luck
