From 02:45:873 to 02:56:844, there's very wrong snaps, missing notes and inconsistent usage of LNs. The density is unnecessary, as there's sounds that are represented wrong, the length of the LNs is incorrect in most cases, there's a unnecessary amount of shields, minijacks and weird snaps that make this part feel completely off.
Might do something similar to the rework for 04:23
From 03:31:544 to 03:39:544, has weird usage of LNs, the LN at 03:38:544 (218544|0) ends too early, not representing the sound and feeling uncomfortable to release. Use rice notes.
03:42:669 - Missing notes.
Like, some of the notes represented sounds that are either inaudible by the normal player or represented them earlier than it should've been. It's quite normal to see those issues.
02:40:558 (160558|0,160601|1,160730|0,160730|1,160858|1,160901|0) - As Dubstek mentioned in his mod, the usage of anchored LNs is quite unnecessary, this happens with the usage of unnecessary LNs to hold for a sound that could be easily represented with 1/4th LNs or more varied rice. Try to vary the patterns more.
02:45:015 - Sound not charted, use a rice note or a LN. Same as 02:45:358, try to remove the rice note that there's immediately after, it can create a unnecessary shield.
From 02:33:530 to 02:40:387 - I would suggest a little revamp for this section, at 02:35:544 there's notes which are missing to represent some of the sounds of the song, which effectively makes the section feel off when played. Here's my suggestion: https://cdn.discordapp.com/attachments/1119427500783706202/1145452285401510060/image.png
Whilst on 02:36:787, the snaps are completely off. (Before: https://cdn.discordapp.com/attachments/1119427500783706202/1145452671176814602/image.png), it doesn't match the length of the sound, and neither does it play with a good synchronization. Here's my suggestion for this one: https://cdn.discordapp.com/attachments/1119427500783706202/1145452453228183632/image.png (Use 1/8th snap)
There's also unnecessary notes, which don't represent anything in the song, like on 02:37:758 (157758|1). On 02:39:015 (159015|1,159101|2,159187|1), the LNs have a inconsistent length which make them not match the sound in a proper way.
02:32:844 (152844|1) - Add a LN, sound isn't represented, not even by rice notes. Also, for 02:33:187 (153187|3,153187|2), make LNs longer and add a LN to 02:33:358 (153358|0) to make a transition to the next section.
02:24:958 (144958|2,144958|3) - Add a LN note and a rice note and add two LNs to 02:26:330 (146330|2,146501|1). This is for representing the piano.
02:22:387 (142387|0,142387|3,142387|3,142473|0,142473|2) - Notes missing to represent the sound, pattern suggestion: https://cdn.discordapp.com/attachments/1119427500783706202/1145450692820082818/image.png
02:21:615 (141615|3) - Replace the two rice notes with a 1/4th LN note to represent the vocal better.
02:20:673 (140673|0,140758|2,140758|3) - Incorrect snapping and lack of representation of the sound. Add new notes that are snapped in 1/4th.
02:19:558 (139558|1) - Sound isn't represented, I recommend putting a note in a 1/4th snapping to match the sounds of the song, which is mainly working in a 1/4th snap.
02:19:987 (139987|3,139987|2,140073|0,140073|1,140158|3,140158|0,140158|2) - Same issue as 02:19:558 (139558|1).
02:20:330 (140330|3,140330|0) - Same issue as 02:19:558 (139558|1) and 02:19:987 (139987|3,139987|2,140073|0,140073|1,140158|3,140158|0,140158|2).
02:06:144 (126144|3,126487|0) - Inconsistent LN length, would make more sense if the LNs were longer or at least had a different purpose than just being a short LN, I would suggest to convert them to rice notes or to be a little longer, if using LNs is the mappers' intention to represent the sound.
01:51:187 - Wrong snapping in the LNs, doesn't match the music properly. (https://cdn.discordapp.com/attachments/1119427500783706202/1145446723490164817/image.png, left = wrong snap, right = corrected snapping/pattern suggestion)
01:47:073 (107073|0,107073|1,107073|3,107223|3,107223|0,107223|2) - Doesn't match the sound in the song, I would suggest to change it to something like this (https://cdn.discordapp.com/attachments/1119427500783706202/1145445455979876463/image.png use image for reference) to match the sound better.
01:48:615 (108615|3,108615|2,108615|0,108615|1,108744|2,108787|1,108873|2,108958|2,108958|0,108958|1,108958|3,109044|2,109044|0,109130|1,109130|3) - Lacks consistency in the pattern, skips a sound.
00:51:826 (51826|2,51920|2) - 00:56:983 (56983|0,56983|1,57108|0,57108|1) - 00:57:233 (57233|3,57233|2,57358|3,57358|2) - 00:57:483 (57483|0,57483|1,57608|0,57608|1) - 01:03:451 (63451|2) - Incorrect LN length usage and unnecessary shields, try to make the patterns more varied and express the LN length with the sounds of the song, not just making LNs to be LNs.
Also, for 01:28:983 - The sound isn't charted unless expressing with release.
04:19:294 (259294|2,259294|0,259294|1,259419|1,259419|3) - Same issue, inconsistent releases.
04:23:544 (263544|0,263544|3,263606|0,263669|1,263669|2,263731|3,263731|1,263794|0,263794|2,263856|0,263919|3,263919|2,263981|2,264044|1,264044|0,264106|3,264106|1,264169|2,264169|0,264231|1,264294|2,264325|3,264356|2,264387|1,264419|3,264419|0,264481|2,264481|1,264544|3,264544|1,264606|0,264606|2,264669|2,264669|3,264731|0,264731|1,264794|3,264856|1,264856|2,264919|3,264919|0,264981|2,265044|0,265044|1,265106|3,265106|2,265169|0,265231|1,265231|2,265294|0,265325|1,265356|2,265387|3,265419|1,265450|0,265481|3,265512|2) - Unnecessary shields, minijacks, and snaps that don't contribute anything to the song representation, might need to rechart.
1/4th and 1/8th charting, try to do a simpler pattern without that many shields.
Make a little stream of 1/8th notes with some LN density sprinkled into it, might be better, but replace the minijacks with other patterns.
03:53:544 (233544|0,233544|3,233637|2,233669|1,233762|3,233794|0,233856|1,233981|2,234169|2,234294|1,234356|2,234481|3) - Weird snaps, doesn't match the song's rhythm.
03:58:544 (238544|3,238544|0,238544|1,238544|2,238669|2,238669|0,238669|3,238794|3,238794|0,238794|1,238919|3,238919|0,238919|1,238919|2,239044|2,239044|3,239044|0,239044|1) - Inconsistent releases, would've been better to replace the 1/12th length LNs for rice notes as it doesn't add anything to the chart, only LN count.
After some moments, I have another suggestion.
Change difficulty name to "Light-years away". Might look better and also work correctly in terms of spelling.
(This just sounds like the average "nerd emoji" type of bullshit.)
