Hey~
[General]
The approach circle is really hard to see at some points
Custom

Default

I would prefer if you used the
default one in this case. It becomes much clearer

Rename to
Lunatic?
00:22:357 (1) - finish on start
01:10:786 - add something for better flow
01:20:643 (1) - ^
01:21:500 (1) - remove NC
01:22:143 (6) - NC
01:30:071 (1) - remove NC
01:34:143 (5,6,1) - NC on (5) instead
01:48:071 (1,2,3,4,5,6,7,8,9) - This polygon shaped pattern looks inaccurate. You can make one perfectly symmetric with "Create Polygon Circles"
02:01:786 (1) - finish
02:04:786 (1) - ^
02:05:000 (2) - NC
02:12:071 (3) - Finish on start
02:13:786 (4) - ^
02:19:357 - add something here to make it flow better?
02:42:714 (6,7,1) - NC on (6) instead
02:51:286 (6,7,1) - ^
02:53:000 (6,7,1) - ^
03:26:428 (1,2,3,4,5,6,7,8) - I find this part kinda weird
03:54:071 (1) - Remove NC
[Regou]
00:06:928 (3,4,1) - Please use 1,0x spacing. 0,5x is really confusing and so tight imo
00:54:071 (1,2,3,4) - I suggest you go straight instead of changing direction in the center
01:12:821 (5,6) - Would you be kind and use 1,0x instead? Yeah I know it's 1/4, but still. Tight doesn't always makes it secure
01:23:107 (5,6,1) - space it up a bit
01:26:535 (4,5) - ^
01:30:500 (5,1) - ^
01:36:821 (5,6) - ^
02:21:393 (5,6) - ^
02:31:678 (5,6,1) - ^ these 3 slider sections are more important because it looks like a lump
02:45:393 (3,4) - ^
02:46:143 (5,6,1) - NC on (5) instead
02:53:000 (4,5,1) - NC on (4) instead
03:18:928 (3,4,1) - this looks so crowded
03:29:964 (4,5) - separate a bit
03:47:857 (3,4,1) - NC on (3) instead
03:54:178 (4,5,6,7,8,9) - weird finale. A repeat, and then a stream

[Normal]
Use AR 5, feels much better overall imo
00:12:928 (2) - finish on end
00:17:214 (4,5,1) - odd spacing
00:22:357 (1) - finish on start
00:27:500 (2) - finish on start & end
00:44:643 (3) - remove finish from start
00:53:214 (1) - remove finish
00:56:428 (1) - remove? Offbeat notes are not that nice after a spinner
01:06:500 (1) - finish on end
01:07:357 (2) - ^
01:21:500 (3) - finish on start & end
01:27:500 (1) - finish on start
01:34:357 (1) - ^
01:35:214 (3) - ^
01:36:071 (4) - ^
01:57:500 (3,4,1) - spacing looks uneven here
01:58:357 (1,2,3,4,5,6) - ^ here as well
02:05:000 (1) - I suggest you remove this one, it becomes too stressy
02:08:643 (1) - finish on start
02:12:071 (1) - ^
02:13:785 (3) - ^
02:15:500 (1) - ^
02:19:571 (1) - remove this as well?
02:30:071 (3) - finish
02:30:928 (5) - ^
02:36:071 (1) - finish on start
02:39:500 (1) - ^
02:43:786 (1) - ^
02:44:643 (2) - finish
03:14:428 (1) - remove?
03:21:500 (2) - I see no point with a finish here imo
03:24:928 (3) - finish on start
03:38:643 (3) - finish on start & end
03:46:357 (1) - finish on start

Good luck :3
