could think about rhythm focus.
00:16:826 (5,6,7) - 00:19:767 (4,5,6,7) - 00:23:100 (5,6,7) - 00:41:924 (3,4,5,6) - 00:55:649 (3,4,5,6) - 00:57:218 (7,1,2,3) - 01:01:924 (4,5) - 01:08:198 (3,4,5,6) - 01:12:512 (7) - 01:15:649 (6,7) - 01:19:571 (1,2,3,4,5,6) etc
There is a tendency for some vocals or sounds to be ignored by 1/2 sliders or 1/1 sliders. Since you tried to represent drums and vocals at the same time, the focus of the rhythm became awkward.
For example, the vocal start here 00:55:845 and 00:57:414 but it's ignored due to 1/2 slider.
00:49:375 (4,5) - same. The vocal starts here 00:49:571 but it's ignored.
01:19:571 (1,2,3,4,5,6) - also same. Vocals tend to be slightly ignored as 1/2 slider spam. Vocal starts here 01:21:532 and 01:21:532, so I think it's better to make it clickable. The vocals are intense so it's not worth ignoring them.
As in these examples, the choice of rhythm is inconsistent and irregular.
So I think it's better to remove the unnecessary 1/2 and 1/1 sliders (rhythm) and focus more on the vocals.
here is the some example of rhythm that follows vocals
00:41:924 (3,4,5,6) - https://hetosu.s-ul.eu/bMgfnA06
00:49:375 (4,5) - https://hetosu.s-ul.eu/tXihnR08
01:19:571 (1,2,3,4,5,6) - https://hetosu.s-ul.eu/tZzuNKfO
What these rhythms have in common is that removed unnecessary 1/2 and 1/1 sliders and focused on vocals consistently.
I am worried that the rhythm is unnecessarily too dense throughout the map.
00:15:257 vs 00:48:198 - First, the difference in vocal or drum strength between the this two sections is clear, but there's no difference in rhythm. For example, 00:16:434 (4) - 00:18:983 (2,3) - 00:22:120 (2,3) - 00:22:708 (4) - 00:25:257 (2,3) etc. So, you should reduce or remove unnecessary 1/2 rhythm and reduce density overall imo.
Here is my rhythm suggenstion for reducing density.
00:15:257 (1,2,3,4,5,6,7,8,1) - https://hetosu.s-ul.eu/rPwPqKXU
00:24:669 (1,2,3,4,5,6,7) - https://hetosu.s-ul.eu/CUconuK2
It is a rhythm that follows the vocal while giving a density difference, so it'll be a one of the good rhythm to solve the current problem.
There's so many 1/2 rhythm chain or sliders overall the map. As I mentioned above, the rhythm is unnecessarily too dense.
00:10:551 (4,5,6,7,1,2,3,4) - 00:13:689 (5,6,7,8,1) - 00:32:904 (4,5,6,1,2,3,4) - 01:14:473 (3,4,5,6,7) - 01:24:276 (4,5,6,7,1,2,3,4) - etc
So, I think the rhythm needs to be simplified a bit. My suggestion is to replace the 1/2 slider with a circle or 1/1 slider in part.
For example:
00:10:551 (4,5,6,7,1,2,3,4) - https://hetosu.s-ul.eu/AQVcf57p
00:48:198 (1,2,3,4,5,6,7,1) - https://hetosu.s-ul.eu/BR217eJo
It simply changed the 1/2 slider to a circle or slider, but the density reduces or the rhythm is simplified.
