00:07:701 (1) - Maybe no NC here its still in the previous piano melodic phrase
00:11:407 (1) - Same
00:22:527 - Maybe on circle here just at this 00:22:758 (1) slider head, since the piano actually starts here
00:26:928 (4,1) - Maybe those 2 are a bit too far away for a regarding the spacing you are usually using, try decreasing it to 2.2 or less i think
00:49:168 (7) - Maybe you should move this one to the head of the next sliders, just to contrast with all the blankets you are using
00:51:253 (1,2) + 00:51:484 (2,3) - Thats too big jump in a row, i mean it alright to have difficulties in a map of course but it some how pop out of nowhere since you are using a spacing much smaller before... maybe try to reduce a bit one of those jumps
01:10:712 (5,6,7) - Um okay im pretty sure those can of jump are more for 4.5* maps xD so i dont know maybe reduce them a bit
01:43:840 (5) - This one is just a bit too high, it can collide with the life bar of certain skins be careful
01:56:813 (2,3,1,1) - You are going too far beyond the 4:3 boudary :s
There are few more circle almost half out this boundary that i think you should fix too but i wont paste them all here you can find them easily
02:01:214 (4) - A coming back slider would be more appropriate to follow the singing
02:20:442 (2,3) - I would have those 2 more far away since in really the moment when the singer goes the highest
02:20:674 (3,4) - And then less spacing there since its the end of the melodic phrase
02:28:318 (3,4) - This spacing is really weird, you used the same kind of spacing before but it was during a small music climax and surrounded by increasing spacing jump, but in this case 02:27:855 (1,2,3) are really regular and suddenly a huge spacing
03:04:457 (1) - Not sure a NC is really relevant here
03:10:249 (1) - Maybe move this one at the head of the next slider
03:25:770 (4) - NC
03:26:465 (7) - And here too
03:50:789 (1) - This is really weird, the slider end when it should start, it think you should go for something like this (at 03:50:558) :
04:26:002 (8) - Maybe move it just a bit to the lower left (around x:340-345 y:205-209) so the reading will be less confusing
05:00:982 - Add a circle here since we are in the kiai time now
05:13:955 (4,5) - Those 2 are really too far away for no special reason i think
05:15:809 - Same as 05:00:982 here, so it creates a contrast with the moment where you have 1 circles before the chorus restarts singing
Really clean mapping overall, there are still work with the hitsounding anyway, really interesting patterns so yup good job eheh :3
