Extra:
Rhythm and spacing:
00:12:143 (2) - There are three beats that fall on this slider, yet only the weaker ones on the red ticks are supported by the slider. This is a bad way of emphasizing the music. Therefore, I would suggest you take the note on the beat into account by replacing this slider with three circles or a 1/2 slider followed by one circle.
00:13:433 (6) - This slider is on the offbeat as well. Change 00:13:433 (6,7) to circle-slider instead of slider-circle.
00:13:917 (8,9) - ^ but the other way around.
00:14:401 (1,2) - ^
00:15:206 (4,5) - ^
00:16:174 (8,9) - ^
00:16:336 (9,10) - unpredictable 1/4 jump
00:16:578 (10,12,14) - there is no actual sound on those blue ticks, remove this stream and you'll also get rid of the issue mentioned above.
00:16:901 (14,1,2) - Offbeat stuff as mentioned in the beginning.
00:17:787 (3,4) - ^
00:18:433 (6,7,8) - ^
00:19:965 (12) - unreadable as this 1/4 jump doesn't have less spacing than the 1/2 spacing before
00:19:965 (12,1,2,3,4,5,6,7,8,9,10,11,12,13) - no notes on the blue ticks, remove this stream
00:22:062 (5) - no sound on this one
00:22:143 (6) - there is a drum sound on the blue tick in this slider. Consider emphasizing that by converting this slider into a triple.
00:22:143 (6,7,8,9) - actually the whole section consists of 1/4 drum notes so you can place a longer stream as well.
00:22:949 (9) - ugly slider. Use red anchors for the first curve and don't delete the gray slider points. Also, don't let the slider end on a red tick as that's not emphasizing anything in the music.
00:27:788 (1,2) - Offbeat again. You could nicely emphasize the lyrics if you were to change the place so the slider isn't on the red ticks.
00:29:078 (6,7) - ^
00:30:127 (2) - No sound here again
00:33:756 (12) - Offbeat again
00:35:530 (3,4) - ^
00:36:981 (1,2) - ^
00:38:433 (9,10) - no reason not to emphasize every white tick by a clickable object. Consider replacing the reverse sliders by normal slider and circle combinations so that the sliders all start at white ticks. Also, consider emphasizing the "Hai" in the lyrics as well as it's quite important in the music.
00:39:723 (2,3) - Offbeat yet again
00:41:175 (1,2) - ^
00:41:981 (4,5) - ^
00:46:014 (2) - ^ really bad case of offbeat actually. Also, I won't point out the other cases of offbeat as well as I think you got the point. Just start every slider on a white tick for this song.
00:51:014 (8,9) - Consider mapping the 1/4 drum notes as a stream for this part.
00:53:514 (10) - No sound here
00:58:998 (10,11) - No sound here as well
01:00:046 (5,6) - Decrease spacing as there is no indication that that's going to be a 1/4 jump.
01:00:448 (7,8,9,10,11,12,13,1,2) - No sound on the blue ticks yet again
01:01:659 (4,5,6) - No sound for 5 but a note on a blue tick in 6. Consider mapping the drum notes properly.
01:03:352 (2) - No sound again
01:06:337 (1) - Consider emphasizing the "Hai" sound again
01:07:627 (1,2) - ^
01:09:401 (4,5,6,7,8,9,10,11,12,13,1) - What is that supposed to be? No sound on 01:09:481 (5,7,11) . The shape doesn't make sense nor does it look good. Remap this part.
01:12:304 (3) - Consider mapping this slider as a triple like you did because of the lyrics before.
01:28:110 (9,10,1) - Consider mapping out the drum beats instead of overmapping those triples in the whole section.
01:33:110 (13) - Let it end 1/2 beat earlier so it's on the beat aswell.
Aesthetics:
(This is primarily for ideas as most of those patterns would probably be remapped if you followed the rhythm and spacing points.)
00:13:433 (6) - Don't place objects in the same place as others which were played 1s before that because overlaps don't look very well.
00:14:884 (3,4,5) - You could make a proper triangle out of the slider ends and the circle
00:17:465 (2,4) - Straight diagonal sliders don't look well, change their angles.
00:19:724 (11,12) - You could make a blanket
00:27:949 (2,3) - ^
00:31:659 (1,4) - Another case of overlap.
00:33:756 (12,14) - ^
00:34:562 (1,2) - ^ (not quite, but doesn't look good, increase the spacing.)
00:43:756 (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15) - create streams using some tool like the slider conversion tool.
00:45:207 (1) - Doesn't look good because of those sharp angle red anchors.
01:12:949 (6,7,8,9,10) - You could make a triangle out of this.
01:23:594 (5) - I think you wanted to make a nice curved slider but you should place the white slider points further apart and in another angle for it to properly work.
Generally, you should try to make actual patterns and not just place the circles somewhere you think is an appropriate place.
Flow:
(again primarily for ideas)
00:15:690 (6,7) - Angle is too dull
00:17:465 (2,3,4) - ^
00:19:401 (10,11,12) - ^
00:59:562 (3,4,5) - ^
01:03:272 (1,2,3,4) - Why is there such a low spacing after a jump?
01:11:175 (8,9,10,11,12,13) - Really hard to hit
01:13:433 (10,1) - Don't understand the reasoning for this jump
