turn off grid snap. it isn't useful and makes blankets and directional things messed up, like 00:48:661 (1,1) - or 00:41:714 (3,4) -
00:16:135 (3) - you could make this shape look nicer. try to avoid the corner near the head by smoothing that whole curve out so it doesn't have the angle
00:20:240 (1,2,3) - you should make 2 a blanket on 1's tail, and make 3's tail at the same spot as 1 so that all the shapes blanket (use the same slider curve for each)
00:29:082 (1) - use extra low SV for this slider? also you could make it look nicer, this shape is kinda lazy
00:39:819 (3) - would flow better if you rotated the slider shape like -40 degrees
00:41:714 (3,4) - 3 should point directly at 4 (its a little off because of grid snap)
00:51:194 (2,4) - could be spaced more so not so cramped
00:54:036 (4,1) - all other times you space these out quite a bit, so this overlap doesnt fit
01:02:879 (3,4) - improvable blanket
01:04:773 (3,4) - 3 should point perfectly at 4
01:02:879 (3) - should probably be a 1/2 slider to match 01:04:773 (3,4) - (same piano rhythms, both have an emphasized melody note on 3)
01:06:036 (3) - shouldd probably also be a 1/2 slider since 01:06:984 (4,5) - have rhythms mapped to them, but the red tick 01:06:352 here doesnt
01:07:931 (1) - ^
01:07:931 (1,2) - fix blanket
01:11:089 (5) - this should be 2 circles since you're focusing on the higher-octave melody here (the red tick has an important sound)
01:18:668 (5,6,7,8,9) - doesn't flow well
01:21:036 (1,2,3) - this triple starts on the white tick, and it should technically be 1/6, but simplifying to 1/8 is fine, too.
01:19:300 (9,1) - why is nothing mapped between these ticks? you follow these piano notes here: 01:06:984 (4,5) - 01:08:879 (2,3) - etc.
01:23:089 - this section until 01:49:615 (1) - is vastly overmapped in the context of the map. this would be a difficult pattern even in many 5 star maps. this part is not drastically more energetic or climactic than the rest of the song, its only more rhythmically dense. i would consider remapping this. same goes for the second occurence (i should also mention that the bookmark section from 01:23:089 - to 01:38:247 - is the same as 03:49:864 - here to 04:05:021 - but the second time you use sliders instead of circles, which is a much more fitting pattern for the map anyways.
01:43:931 (1,2,3) - why do you stop the 1/4 rhythm here but not 01:28:773 (1,2,3,4,1,2,3,4,1,2,3,4) - here, when they have the same sound that you are following? unless this is supposed to follow the strings, i dont see the reason, but there is only one chord held in the strings here, so this rhythm wouldnt fit.
01:36:984 (7,9) - avoid this slight overlap, looks messy
01:45:826 (1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,1) - these stacks make this nearly impossible and extremely uncomfortable to play, yuo basically have to learn the pattern and play it rather than read it and play it
01:57:194 - everything in this bookmark section is 20ms early or so, you need an extra red tick. or just move 02:18:070 - this one to 117,218 (01:57:218)
01:59:089 (5,1) - fix blanket
02:02:879 (5,1) - ^
02:08:563 (1,2) - ^
02:18:625 (1) - 02:25:292 (1) - 02:31:958 (1) - etc. fits better as 2 1/2 sliders, both of the orchestral sounds are pretty important, i think they should be clickable. all other sounds liket his in the section are clickable
02:21:403 (4,5) - fix blanket and avoid slight overlap
02:50:570 (1,2,3,4,5,6,7) - the sound the stream starts on is here: 02:50:292 - , so you should either have the stream start there and the slider end earlier, or put a circle between the slider and where the stream starts currently.
03:09:736 (1) - unnecessary NC
03:14:736 (1,1) - remove NC on one of the two
03:20:917 (6) - this slider removes the emphasis that is on 03:21:443 - in the music.
03:22:759 (5) - same deal with this slider, theres nothing that indicates this shouldnt be two circles, and the slider removes the emphasis that the tail of the sldier has in the music, since you aren't clicking there. same with 03:24:075 (7,5) - and so on
03:30:128 (1,2) - the tails of these sliders should be clickable, the white ticks are more important musically than the red ticks here
03:40:391 (7,1) - the slider should start where 7 is, thats where the piano begins its arpeggio/chord
03:46:707 (1) - i think you could come up witha better shape
03:49:864 - for this section you should only NC every 6, or always nc every 3 (see: 03:54:600 (1) - 03:56:495 (1) - )
04:12:600 (1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,1) - this is far too cramped, it feels ugly as a pattern and doesn't feel very pleasant visually or in terms of playability
04:23:969 - everything in this bookmark is ~30ms early as well
04:34:390 (7) - 02:07:615 (4) - compare
04:37:232 (4,5) - why are these spaced but 04:38:495 (5,6) - stacked?
04:39:127 (6,1) - swap NC
04:52:554 (1,2,3,4,5) - an angle change would be nice so this part looks/plays different than 04:51:449 (3,4,5,6,7,8,9) - to highlight the musical change
05:00:442 - this red tick should be at 04:59:887 -
05:08:775 (3,4,5) - 4 should be in the center of both sliders
05:18:219 (5,1,2,3,4,5,6,7) - same as before
05:23:219 (1) - i think it would make much more sense for the tail to be clickable here, its probably one of the most important sounds in the music
05:33:775 (3,1) - space 1 farther away from the slider, and blanket accordingly
05:36:553 (1) - this slider doesn't look great
05:44:886 (1) - add a 1/8 triple to highlight the piano like you do before?
05:46:553 - in this section i think you should highlight whats going on in the background of the music as well, since its setting the tone while the piano just repeats. like these sounds: 05:48:775 (1) - and the pizzicato violin
good luck!
