since this is an easy diff, you might want to provide some breathing room for the players in the main sections.
The section is based off a 140 BPM 1/2 note chain (260 BPM 1/1) and might want to take some pointers from RC normal guidelines (yes, this is an Easy but the suggestion stands).
"Long streams of 1/2 notes should include, at minimum, a 1/1 pause where natural to implement after every musical phrase, as these can become too physically demanding for players at this level."
Therefore for the two main speedcore sections, you might want to use some short breaks from time to time.
You can delete these notes for a more balanced Easy diff:
00:17:360 (17360|1) -
00:19:206 (19206|0) -
00:21:052 (21052|0) -
etc
Same idea for
01:34:206 -
This is so that these speedcore sections are less diffspiky
For kiai #2:
Compared to the other two kiais, the density took a nosedive for a rather intense and highlighted section. You should consider adding a few 1/1s for better pacing. I suggest a 3-note chain approach to this section. You can also make the 3-note chains less common if you want

this is just an idea you dont have to follow it 1:1. You can mix it up as well if you want.
