sorry for late
suggestion, only change if you feel like it

title should be "Sorairo concerto", yes. it is not incorrect if the artist itself has stated this to be the translated title.i would have used soft hitsound with a light snare drum hitsound on beats 2/4 here, i'm aware it's not in the song but it would be a very nice addition since as it is you just have whistle/bell hitsounds. it is not necessary to change this, just keep in mind for future maps.

00:19:261 (2) - imo, c/p from 00:18:156 (1) would make more sense:
http://puu.sh/lXvnp/3282d58626.jpg01:03:800 (4) - flow here could be improved imo. what do you think of this...

01:15:579 (4) - ^
http://puu.sh/lXvj9/30b0a91c08.jpg01:21:101 (2) - c/p from 01:19:997 (1) ?
http://puu.sh/lXvl9/1293f2f650.jpg[Normal]
00:22:757 (5,6,7) - i would advise against using 3-stack in Normal diff. it's kind of boring to play, and in the case of a Normal diff, if you have that many notes in a row, it's usually easier for beginner to hit a less complicated rhythm. imo, either space it out or use a kind of rhythm more similar to this:
http://puu.sh/lXvLv/c08a3f44cc.jpg00:25:702 (5,6,7) - ^. i will not point out all of these.
note, i would say 00:28:647 (5,6,7) is OK bc it's more interesting than just basic stack, so it's probably better to leave it.
00:43:371 (4) - for "combined curve" slider, imo aesthetic is better if curve is more defined. example
https://osu.ppy.sh/ss/4142278[Hard]
00:32:512 (4) - could easily make this blanket better:
http://puu.sh/lXvwz/f58f43df56.jpg00:37:481 (2,3,4) - this jump doesn't seem to fit imo, it's the only time in this section you make a jump like this. why not just use same rhythm as before?
01:30:303 (1,2,3,4,5) - imo this doesn't really fit the "rising" atmosphere ur building in the song... u could easily do sth like this...
https://osu.ppy.sh/ss/4142265 or any number of similar pattern.
[Intense]
00:13:371 (6,1) - what do you think about using a 1/1 slider here instead? fits the song way better imo.
00:15:764 (4) - this slider doesn't flow well with the previous notes, since it's curved differently. better would be sth more like this...
http://puu.sh/lXxbv/6277e35098.jpg don't forget fix spacing after
00:21:285 (2,3,4,5,6,7) - i know it's for pattern, but it is not good to make notes closer than base DS (1.2x). this kind of pattern is usually done by spacing the "close" notes at the regular distance, to keep the structure of the map consistent.
00:24:230 (2,3,4,5,6,7) - ^ i will not point out all of these.
00:26:070 (4,5,6) - spacing error?
00:29:567 (6) - now, for this one, imo just a hitcircle would be better to make the rhythm starting from 00:29:935 to be more distinct.
00:34:905 (4,5,6) - i really think you could make some more variable rhythm here. consistency is good, but you've used the same rhythm in the map for this every single time. even sth like this...
http://puu.sh/lXxpj/d33ab60989.jpg to create some variance in the map would be good (in this case you could also make a jump on (5)). there are several ways to fix this, but this kind of thing applies to every one of these rhythms (even the ones before if you wish) so do sth suitable for yourself.
00:37:113 (1,2,3,4,5,6) - this, for example, was much more interesting.
00:41:346 (6) - same as 00:29:567 (6) .
00:47:052 (5,6,7) - again, i don't think 3-stack is suitable here. for an Insane diff, you can make some more interesting pattern than a long stack. using some different rhythm, again, could give you some better idea for this part and make the map more interesting, for example...
http://puu.sh/lXxzX/f1018fd049.jpg .
00:56:070 (5,6,7,8,9) - again, long stack is kinda boring... what do you think about a kickslider here?
http://puu.sh/lXxFx/bd946fe999.jpg would be a good way to transition to the slow part, imo.
01:03:248 (4,5) - spacing error?
01:25:886 (1,2,3,4,5,6,7,1,2,3,4,5,6,7,8) - i'm really meh on this. i get that you want to make some jumps here to match with the song but the placement feels kind of random. if you're going to do sth like this, i would recommend this...
https://osu.ppy.sh/ss/4142483 ... would flow so much better since it fits into one pattern.
01:27:359 (1) - now, when you switch pattern here, a more intuitive way to do this would be to transition using some slider, or any kind of different rhythm; the switch in rhythm would make the pattern change more noticeable than just placing the hitcircles differently. i think this...
http://puu.sh/lXyJ6/decde2fcd0.jpg would not only be intuitive, but also more sense pattern-wise (circles -> sliders -> circles) and consistent with 01:31:776 .
01:31:776 (1,2,3,4) - again, i can't comprehend the shape behind this. the song has a "rising" atmosphere here, and "free" placement doesn't fit very well - better to keep a well-defined structure to fit the tenseness. imo, sth like this...
https://osu.ppy.sh/ss/4142449 would be perfect for this part.
01:34:721 (1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1,2) - this is so much better and is very intuitive to play since the arrangement of the notes is clear.
01:37:665 (1,2) - what do you think about this placement...
https://osu.ppy.sh/ss/4142505 ?
[Insane]
... i don't know how to mod this.
imo, the map needs some work, structurally... seems all notes are placed at a different spacing without regard to DS. jumps are fine, but when all the notes are like this, it makes the map very unintuitive bc there's no structure or consistency anywhere. it seems you use 1.3x as base DS starting from 00:00:856 - here. then, at 00:06:377 (1) - you use anywhere from 1.4x ~ 1.5x which is fine enough, but then at 00:18:156 (1) is 1.2x which is very wrong since it doesn't seem have any reason behind it. 00:22:389 (1,2,3,4) is also 1.2x, it should be 1.4x like the rest. it seems this continue through the rest of the map, would be so much more intuitive if it was unified (using the same or a more similar one for everything).
what i said in Intense about rhythm/pattern also applies here, it would be much more interesting to make some more variable rhythm, it is possible even if song sounds the same.
i do not want to force my style on the map, so instead i'll just say if you accepted most things on Intense, you should really look through here to see sth suitable for yourself.
i hope this was useful, you can rank this if you work hard enough and look into the issues on Intense/Insane i think.
good luck ~
