00:25:400 (4,1,2,3) - I believe the beginning was principally following the vocals, but this slider 00:25:719 (1) - is emphasizing the piano. What about following one layer here and offering a little break time?
for the part at 00:26:358 i did a 1/1 slider instead to be consistent with 00:21:890 (2) since i feel that a 1/2 reverse + circle followed by 00:26:996 (1,2,3) might be too intense for the this part of the song
would replacing 00:25:400 (4,1) with a 1/1 reverse slider to passively map the piano work instead, since i also passively mapped the piano in later sections? i'm not sure if i like the 2/1 break there
00:28:432 (1,2) - 00:35:453 (3,4) - 00:42:156 (6,1) - Should be stacked similar to how your other 1/2 gaps after circles are handled (e.g. 00:35:453 (3,4) - 00:45:188 (2,3) - )
00:34:656 (1,2,3,4) - Stacking objects are not a bad idea, but I'm thinking this could be a little confusing because the first circle is not stacked (for obvious reasons..). In this case, I would recommend unstacking objects 3-4. The rhythm choice will be easier to find with 2-3.
00:43:113 (3,4) - Nerf this section by removing the circle and adding a reverse arrow. That'll make a clearer distinction for the rhythms landing on red ticks.
00:52:209 (3,1) - + 02:03:698 (3,1) - Despite the editor showing that the spacing is the same, we need to take into account the SV change which makes the spacing inconsistent. To keep it consistent, these objects should have a difference of 0.82x.
changing the kiai sv to 1.00 to distance snap the objects at 1x then putting the sv back to 1.10 changes the distance to 0.9x, so i did 0.9x instead (unless i'm missing something?)
01:01:145 (4,1,2,3) - 02:33:060 (4,5,6,7) - This pattern is confusing to new players due to the similar distance between notes, I suggest spacing the circles apart more
01:31:464 (2) - circle + 1/1 reverse on 01:31:783 - would be nicer so you catch the vocal and let the part without vocals play passive instead
02:16:305 (3) - since its chorus you could turn this into 1/2 + circle instead to have snare on slider tail and make the vocal active too - keeps the intensity up a bit
