Hey I was snooping around some modding queues and felt like posting some information for you to look at:
General
The timing is incorrect. You need to make your uninherited timing point start on 00:00:500 - because as it is right now, the downbeats are on the wrong beat , so moving it to where I suggested it would line up all the beats. (and fix nightcore lol)
Right now your background is not working properly, what you need to do is go into your .osu file (for each difficulty) and in "[Events]" you need to change the name of the background image to match the actual name of the background image that exists in the song folder.
Normal
If you press ctrl+a you will notice you have most of your objects in the center of the screen, this can make the map feel a bit cluttered when playing it, and potentially less fun because there are sections of the screen you don't move to.
Overall your 1/2 spacing is a bit high, I think you should have a certain spacing where the objects in 1/2 overlap eachother.
00:03:500 (1) - you should lower the overall New Combo (NC) density for this section since its much calmer
00:00:500 (1,2) - the issue here is, after the player(at this skill level) reaches 00:01:000 - the next slider appears 00:02:000 (2) - and (2)'s tail is closer to the tail of (1). This means that the player will attempt to hit (2)'s tail instead of moving on to (2)'s head. I suggest you move 00:02:000 (2) - up more, and ctrl+g it.
This is a general issue throughout the map, though here are a few points withing the first section: 00:07:500 (2,3) - 00:10:000 (2) - 00:15:000 (4) - 00:19:000 (2,3,4) - 00:25:500 (2,3,4) - the issue here is, the direction at which the cursor is required to move after slider (2) and the direction the cursor is required to move during the slider (3) is inverted. This is uncomfortable for newer players and rather difficult.you should ctrl+g 00:08:500 (3) - ( and fix spacing accordingly)
This is a general issue throughout the map, though here are a few points withing the first section: 00:08:500 (3) - 00:10:000 (2) - 00:15:000 (4) - 00:20:500 (4) - 00:22:000 (2) - I found skipping the sound at 00:08:750 - to be an issue because you followed the same sound accurately with the previous two sliders at 00:06:500 (1,2) -
00:13:500 (2) - 00:25:500 (2) - You can more accurately represent the flute here by making a 1/2 slider starting at 00:13:750 - , note if you agree with this comment you should extend the previous slider to the white tick
00:17:000 (2) - you should put this circle more to the left, so that the previous slider points more directly at it. In its current state, it also inverts the movement and can be uncomfortable for newer players.
00:35:000 (3) - It looks like you are trying to get the slider ball to bounce to the beat here, to do that more accurately you need to move the red anchor on top of the slider tick (here is an example:
https://bor.s-ul.eu/Ek5Driow.png)
01:24:250 (1,2) - This is clearly a NC mistake, because you use a 2 measure rule where every two measures there is a NC, this NC lands on the red tick prior to the end of the second measure that it's in. I would swap the NC here.
01:45:000 (6,1,2,3,4,5,1,2,3,4,5,6,1) - 01:45:000 (6,1,2,3,4,5,1,2,3,4,5,6,1) - This is a really long chain of 1/2 objects, according to the ranking criteria this is unrankable because the players at this skill level will find it extremely difficult to maintain holding down keys for a extended period of time like this.
01:54:500 - you should map until this point since this is the end of the song and there are instruments on 01:54:000 - 01:54:250 - and 01:54:500 - that you have mapped to previously and because they are not mapped here it is inconsistent.
Hard
I'm just going to say some general issues here that you should consider:
1. the rhythm density of the intro is the exact same as the later part, but the intro is much calmer, so you should have lower rhythm density (and or spacing) to account for that.
00:13:750 (3) - the visual spacing between 2 and 4 with this object imply that there is a 1/2 beat inbetween both objects, this will cause a reading issue in hard players because the 1/4 rhythm gap will look like a 1/2 rhythm gap. I suggest lowering (3) close to the head of (4) like this
https://bor.s-ul.eu/Hb2eHAkC.png so that issue doesn't happen
00:00:500 (1,2,3) - 00:03:500 (1,2,3) - 00:15:500 (1,2,3,4,5,6,1,2,3) - 00:43:500 (2,3,4,5) - (etc.) the sliders here are much harder to play at this level than you probably intened, because hard players tend to follow the sliders more. This creates much more difficult sections in calmer points of the music than some of the sections in the more intense parts of the music. I find this to be an inaccurate representation of the music.
if you have some issues feel free to pm me and I can try to help you resolve them
best of luck!
