I.R.I.S

00:00:335 (335|1,400|1) - no, I don't care if you wanted to follow the music like this but a straight up 230 bpm minijack at the start is just bad

00:00:465 (465|1) - Why no note here

00:00:595 - I dont feel like this beginning part represents the music as well as it could.

What about something like this: https://osu.ppy.sh/ss/18349598/ebd3

There isnt really any distinct sound to map at 00:00:791 - or 00:01:313 -

00:00:856 (856|1,921|3,987|0,1052|2,1117|1,1182|3) - 1/6

00:01:378 (1378|3,1378|2,1443|3) - , 00:01:639 (1639|2,1639|0,1704|0) - and so on, an absolute abomination, what is the point in mapping like this if you have a trillion different ways to emphasize this sound

00:05:617 (5617|0,5682|1,5748|0) - why adding these into a trill when the actual sounds you represented as this start later?

00:05:813 (5813|3,5878|3,6074|3,6139|3,6334|3,6400|3) - i didnt know i was playing shadows of cats

00:06:595 (6595|2,6661|2) - i think you should remap everything in this section

00:07:182 (7182|2,7248|2,7313|2) - shadows of cats 2

00:07:378 - missing note

00:07:639 (7639|3,7639|2,7639|0,7639|1,7704|1) - there we go again, -18/10 patterns

00:12:269 (12269|3,12302|2,12334|1,12334|0,12334|3,12367|2,12400|1,12432|0,12465|2,12498|1,12530|3,12563|0,12595|2,12595|3,12595|1,12628|0,12661|2,12693|3,12726|1,12758|0,12791|2,12824|1,12856|0,12856|3,12856|2) - 1897 mapping in a nutshell

00:15:237 (15237|0,15302|0,15367|0,15432|0) - anchor here is a neat concept but creates quite the large difficulty spike, especially at this high of a speed, would recommend spreading the notes out here onto different lanes

00:26:487 (26487|0) - remove this it helps represent the synth thingy

00:26:748 (26748|3,26748|1,27008|2,27008|1) - misplaced if its supposed to represent the synth move it to 00:26:813 and 00:27:074
or alternatively make it a ln

00:30:595 - 00:34:182 not sure if this break section is warranted, music is still intense and drums are also just as intense, yet representation is very simplified. you have a slight break section at 00:34:769 which is significantly easier than the rest of the surrounding patterns, so you can probably buff 00:30:595 to match the intensity more

00:34:248 (34248|0,34248|1,34291|2,34291|3,34334|1,34334|0,34378|3,34378|2,34421|0,34421|1,34465|3,34465|2,34508|0,34508|1,34552|3,34552|2,34595|0,34595|1,34639|2,34639|3,34682|1,34682|0,34726|2,34726|3,34769|0,34769|1) probably anchors would represent the sound better

00:57:726 - 00:59:813 is 1/3, I recommend listening to the music more, you can find lots of these types of errors

01:01:900 - 01:03:465 is 1/5th every two notes, like this: https://cdn.discordapp.com/attachments/932014993849868360/1065340436027293788/image.png

01:03:987 - 01:06:074 is 1/3rd notes, not 1/4

01:06:074 - 01:06:595 is in 1/16th snap. Like this: https://cdn.discordapp.com/attachments/932014993849868360/1065342306900774913/image.png

01:06:595 - 01:07:052 is 16th notes, like this: https://cdn.discordapp.com/attachments/932014993849868360/1065342439424012288/image.png

01:08:161 - i refuse to keep modding this, no offense but this needs an entire rework, from start to ending

01:08:356 - 01:09:008 col 3 (1|2|3|4) is almost empty, which makes this area feel very imbalanced, take a look at the minijacks on col 2 compared to col 3, https://osu.ppy.sh/ss/18392776/97bb would recommend rearranging this section to be more evenly distributed

02:06:019 Why is this a quad when the other ones with the same sound are triples?

02:06:319 Should put two extra notes here, because of the same sound being a triple before

02:12:019 - 02:13:226 missed drum sounds here

02:16:819 - 02:18:019 this section is in 1/6 snap

02:17:419 (137419|3,137419|2,138619|0,138619|1,139819|0) - triples would represent the sound better

02:19:219 - 02:19:819 may be 1/6????

02:24:019 - i would lower the emphasis on the chordjacks after this timestamp as the drums are decreasing in intensity and volume

02:33:619 - 02:34:969 can be harder?????because the similar thing around it has 1/12....may be a little hard'-'

02:40:219 (160219|2,160256|1,160294|0,160331|2,160369|1,160406|0,160444|2,160481|1,160519|0,160556|2,160594|1,160631|0,160669|2,160706|1,160744|0,160781|2) -
i know you don’t want to use the 4th line, but ill suggest you to move all the note like this
[ https://cdn.discordapp.com/attachments/1075121515751809084/1075128761604907048/image.png ]
for me this pattern looks easier and cooler to play

02:45:319 (165319|3,165319|2,165319|0,165394|2,165394|0,165394|3,165469|0,165469|1,165469|3,165544|3,165544|1,165544|0) -

this pattern is inhittable and the pitch is not correct [ 'cause you'll can find the same kick here 02:45:919 (165919|0,165919|1) - ] , remove from each handjack one note and chart it as a jumptrill

02:46:069 (166069|3,166069|2,166069|1,166069|0,166219|1,166219|2,166219|3,166369|1,166369|2,166369|0) -
rechart in this way
[ https://cdn.discordapp.com/attachments/1075121515751809084/1075137496658223145/image.png ]

cause :
02:46:069 (166069|0) - you cropped this one at 02:46:219 despite the sound get to 02:46:369
02:46:219 here just the doubles as kicks, there's no reasons for maps the ln's
02:46:369 (166369|0) - this note is strange, i forget into the screenshot but i suggest you to remove this one cause there's no kicks

• 02:48:169 same thing of probably most suggestions, this is unplayable, remove and adjust the notes like this [ https://cdn.discordapp.com/attachments/1075121515751809084/1075140395262021795/image.png ]

02:52:519 it's not like 02:53:869 why do you pitched it as a triplet, this sound like 02:53:719 (173719|3,173719|2) -;
delete 1 note and place the remaining 2 not in the 3th / 4th line,

02:56:494 - 02:56:719 02:59:494 - 02:59:719 these two parts is empty consider maybe a few notes there is
ok because the notes around them express the melody which is lower than drum .(ok you can refuse all my mod bacause i am bad in playing this game either playing map or mapping(if i do something wrong dont angry))

• 03:01:819 to 03:02:344, you cant chart this 230 bpm as a 1/6, this is just impossible to hit with doubles and unplayable, that break 1.2 probably is easier to play than this ...
  i suggest you to rechart like this:
  [ https://cdn.discordapp.com/attachments/1075121515751809084/1075144378336682025/image.png ]
  from 03:01:819 to 03:02:081 chart this as a 1/4 stream without doubles
  from 03:02:119 to 03:02:344 chart this as a 1/2 jt like the screenshot

• 03:02:869 (182869|1,182869|3,182869|2,182869|0,182944|2,182944|1,182944|0,182944|3,183019|0,183019|2,183019|3) - for all this i suggest you to delete just one note, cause the fade out start here, and it'll be more easier to play

04:36:601 - 04:36:987 ...... maybe this density can be a little lower , it lead to a part

05:06:601 - 05:07:043 sorry i dont think it is suitable in the atmosphere:(

• 05:08:366 (308366|1,308366|3,308366|0,308366|2,308587|3,308642|2) - this section should be mapped like this
  [ https://cdn.discordapp.com/attachments/1075121515751809084/1075121547469144125/image.png ]
  05:08:476 is a missing ln of the tune
  05:08:587 here you can use a triplet like 05:08:366 (308366|2,308366|1,308366|3,308366|0) -
  05:08:642 move this ln at 05:08:697

• from 05:17:410 to 05:17:741 i suggest you to spread this pattern like this
  [ https://cdn.discordapp.com/attachments/1075121515751809084/1075123127253733467/image.png ]
  splittrills and pattern like that if you wont delete some notes are impossible to hit ( my opinion )
