02:11:908 same. never use 1/4 slider in normal diff
but want to say something. 02:11:908 (2,3) - 02:13:985 (6,7,8,9) - what will you think about this two timestamp. yes they look same (1/4 slider + circle). but look at the timeline. 02:11:908 (2) slider starts from red line, it plays light sound. but 02:13:985 (6) on the white line. this is downbeat, it plays strong sound.
you can see you use similar thing to represent different sound. this is wrong rhythm, it will hurt playing experience.
ok there is a good example, see 02:15:600 (2,3,4,5). this is after 02:13:985 (6,7,8,9) maybe players will have troubles playing this because there is a wrong rhythm.
this might be happened above Hard. be careful when you want to do rhythm change.
how to change them in Normal. 02:11:908 (2) - use a circle. 02:13:985 (6) - can do a 1/4 reverse (but people would still tell you don't make this. use your way to make it easier). about 02:15:600 (2,3,4,5) - don't know what to do for you, you have your way！
(can't put this to timeline tab so move to here)
00:41:677 (1,2) - never use 1/4 rhythm in normal diff. also never use 1/4 slider 00:42:023 (2) in normal diff too. 01:06:600 (7,8) - just use 1/1 slider, so you don't need that circle. 01:18:369 (1,2) - how will you manage this?
00:12:159 (1,2,3) - only two strong sound just do it with two circles. see other diff, they are sliders for this two sound but they are still one sound one click. 01:03:831 (1,2,3) - same
02:21:138 (2,3) - no sound. can remove 02:21:254 (3). if you want it 5 clicks, 02:21:600 (6) - change to 2 circles.
00:49:523 - 00:56:908 only this section is short sliders (Kiai section). if didn't have reason you can do this from 01:41:677 (6) again
you can ask more people for feedback i think the map is good. who expect a guy being inactive for six months reply 🙂
very random spacing but ok. but three slider 04:07:810 (3,3,3) - are toward the same direction, would be better you can rotate them to change the direction
can buff more. 04:06:610 (1,2,3,1,2,3) - this is powerful but the next one 04:07:610 (1,2,3) you make them easy going ruined the tension of the song. i'd make https://osu.ppy.sh/ss/19199214/146d 04:07:610 (1,2,3,1,2,3,1,2,3) - three group of the pattern the circle are spaced, 04:08:010 (1,2,3) - spacing is slightly bigger than 04:07:610 (1,2,3), and so on (04:08:410 (1,2,3) spaced more). also 04:08:810 (1,2,3,1,2,3) - can control G the circle 04:08:810 (1,2), 04:09:210 (1,2).
the flow isn't fluent as well. i make this https://osu.ppy.sh/ss/19199196/b842 circle is moved away and a slider is extended
