00:18:237 (3) - I dont think you should try to perfectly match the singing here, either end the slider at 00:18:510 or 00:18:646
00:24:373 (3) - You should try to lower this circle, its half off-screen and can appear on the life-bar for certain skin
00:29:419 (8,1) - I find this jump very high for a part with no real music event justifying it
00:38:146 (7) - Just a bit lower so it wont stack with 00:37:600 (5)
00:47:691 (3,4,5,6,1) + 00:48:646 (2,3,4,5) - Try to make those 2 stream the same spacing
01:12:237 (4,5,6,7,1,2,3,4) - Ok maybe its just because im not really good at std, but i find this really hard to read even in AR 9.5
01:30:510 (7) - CTRL+G this one to keep the same feeling as 01:29:691 (4,5)
01:46:636 (7,8) - Same remark as 00:24:373 (3)
01:55:006 (4,5,6,7,8) - I think it would be better to follow the same rythm as 01:54:354 (1,2,3) to create a contrast with the surrounding mapping
02:12:398 (5) - I think you should make start this stream at a place less stacked with 02:11:963 (2,3,4)
02:42:581 (7,8) - They are really stacking with the previous circles (02:41:559 (2,3)) which make the reading hard
02:49:854 (7,8) - Same remark
02:52:581 (3,4,5,6) + 02:53:945 (1,2,3,4) - REALLY NICE >w<)b
03:43:108 (1,2) - Those 2 should be somewhere else, its an unexpected rythm but since its stacking with the previous 03:42:755 (4) its making it confusing
04:37:345 - Move it a bit upper, its stacking with the previous sliders
04:45:422 (2) - I would CTRL+G to have a left-right movement going well with the music
05:06:502 (6) - This one shouldnt go in the same direction as 05:07:061 (1) it makes the reading confuse, it wuld move the slider tail to something like x:196 y:261
05:37:194 (2,3,4) - Maybe you should make this spacing a bit lower, so it wont differ too much from 05:36:496 (3,4,5)
05:45:740 (2,3,4,5,6) - This spacing is confusing because just before we had 05:44:258 (2,3,4,5) which is twice faster but using almost the same spacing
05:47:833 + 05:48:008 - I really expected circles here
07:12:328 (4) - I think a blanket with 07:12:528 (1) could be great here
07:48:620 (3) - Same remark as 00:24:373 (3)
09:24:192 (3,4,5) - You should replace them with a coming-back slider amking the spacing less confusing
09:33:800 (6,7) - Space them more for the climax
10:18:468 (3) - Blanket with 10:18:468 (4)
Really good mapping with lots of great ideas, i wish i could have help you more, but this star rating is already beyond my current level ahah xD
