00:40:153 (3) - for being the easiest diff, this shouldn't overlap with 00:38:953 (1)'s end
01:04:753 (2) - Don't overlap.
01:07:153 (2) - ^
01:28:153 (2,3) - This might be hard to follow for an easy.

Flow break: When the mapping somehow makes the song feel like it stops, but it really doesn't, it's just a mapping silence that doesn't quite go with the song.
Overmapping: Doesn't go with the song, might work in a beatmap context if the sound for the sequence feels right
00:10:453 (1,2) - Flow break
00:22:153 (1,2) - ^
00:31:753 (1,2) - ^
00:40:753 (3,4,5) - Do these need to be at an angle?
00:53:053 (1,2) - Overmapping; No drum nor guitar sound right
01:20:053 (2,3,4) - ^
Make break at 00:57:703 start at 00:58:153
01:32:053 (1) - start at 01:31:753

00:29:953 (2) - Put it where 00:28:153 (3) started maybe.
00:55:453 (1) - Overmapping.
01:12:553 (1,1) - Add a bit more spacing between.
I was told to ignore destroy lol.

00:02:053 (4) - Maybe put this to the right instead of left; side feels a bit cramped

00:06:403 (6,1,2,3) - ^
00:10:678 (7) - ^
00:11:353 (1,2,3,4) - I think these are not aligned perfectly (doesn't matter really, besides this jump is insane)

General
I'd save the Kiai for harder difficulties only; so the improving player can actually feel epic for getting there.
