From my queue ^ ^ just some suggestions~
[General]
Check AI Mod, some inconsistencies.
I really feel that you can make use of the strings in the music to create some good insane difficulty. They are interesting.
Also, consider mapping the intro?
[Hard]
00:18:125 (3,4,5) - Don't like this. would prefer replacing 5 with 2 short sliders (follow string) and a circle. If you want to keep it, try something like this?
00:21:625 (4) - Suggest moving it down a bit so it forms a better pattern with 00:22:125 (5,6) (gonna break ds though, so you may move 00:20:125 (2,3) as well)
00:28:375 (7,8,9) - really awkard. Keep the slider to the end or just replace them with triplets like 00:27:375 (1,2,3,4,5,6)
00:25:875 (3,4,5,6,7,8,9,10,11,12) - not a fan of starting the stream with a slider when there's no obvious stronger beat in the music. really confusing when playing
00:29:875 (2,3,4,5,6,7,8,9,10,11) - ^
00:39:375 (3,4,5) - improve the triangle
00:41:875 (2) - generally you don't want to place the slider end on a strong beat. without clicking the strong beat doesn't feel as strong
00:43:875 (4) - ^
00:47:125 (7,8) - those two should follow the flow created by the previous sliders i.e. move them up a bit to form a better curve
00:47:625 (1,2,3) - improve the triangle here
00:54:375 (3) - don't like this slider
01:02:625 (1,2,3) - doesn't really like this shape
01:04:625 (5,6,7) - when most other objects around are symmetrical these three feel pretty weird
01:08:625 (1,2,3,4) - spacing
[Normal]
Don't like the extra slider tick sound >.<
00:24:125 (7) - blanket issue. Also, don't quite agree with using slider end for two drum hits. Would suggest replacing the slider with a shorter slider + a circle
00:32:875 - add a circle?
00:40:625 (7) - two circles instead?
00:43:125 (4,5,6) - improve the triangle?
01:02:625 (4,5,6) - ^
[Easy]
Just some nazi
00:58:625 (2,3) - blanket
01:00:625 (5,6,1) - triangle
01:03:625 (3,4,5) - spacing
Hope this helps
