01:02:380 (62380|0) - Having a note like this sort of imprisoned can be really awkward to play. I'd recommend something like this or something along these lines: https://imgur.com/a/SNvSpLo . This happens at 01:04:850 (64850|0) - as well.
i know what u mean but i'll keep the ln, cause when i add some ln there it's kinda weird tho
btw there is no vocal there for sure, cause miku say "High Speed" the point that you add there was when miku say "High" that little measure with the melody so you must hear that miku say Hi - igh
02:41:115 (161115|3) - This should be a triple, I'd make 2 LN's 1/4th shorter to fit in a triple there. Something like this https://imgur.com/a/hO0YiNO . I think you get the point as PokeSky also pointed it out a lot, many notes should be doubles or triples. I think you should go through your entire map and look for stronger sounds that only have a single note on them.
02:55:409 (175409|3) - This one should be the same size as 02:54:880 (174880|0,175056|1,175233|2) - (1 Beat long) Ending it on the blue tick makes it kinda awkward and there is no reason to change the size opposed to the LNs at 02:54:880 (174880|0,175056|1,175233|2) -
03:29:909 (209909|2,209997|2) - I think a mini jack like this is quite unjustified here, because you don't really use anymore jacks and it makes it unnecessarily awkward.
for sure these part was added to be ln, but im not updated it as well, since im not logged on osu these day cause gettin sick and tired with some stuff irl :(
