As per your request:
[General]
comboburst-6.png sticks out compared to the rest of the images since the top of the head is cut off. Perhaps find another image of this character?
[Easy]
00:23:809 (2,1,2) - I didn't like the overlap from these. :/
00:48:697 (1,1) - Overlap here doesn't look good either.
00:50:475 (1,2,3,4,1,2,3,4,1) - Felt a bit devoid of hitsounds here. Maybe add a soft whistle to the 4's?
00:57:586 (1) - Eh, kind of short. Might work better as a slider.
01:01:142 (3,4,5) - Even up this spacing
01:09:364 (3,1) - Overlap. :<
01:24:031 (1) - This felt better starting at 01:24:253 -
Strange that this difficulty ends earlier than your other two.
[Normal]
Spacing feels a bit far especially compared to Easy.
00:21:364 (3,4,1) - More overlap~ Eh, I won't point 'em out anymore. You know what to look for by now if you want to change. ;p
00:27:809 (2) - Forget a whistle?
01:09:364 (1) - Kind of felt weird to have sound on a spinner now, haha. Ah well
Overall the patterns are fine, but the rhythms felt a little bland. It felt like I was just playing the same thing the entire song. Especially from 01:20:697 (1) - to the end of the song... it's just quarter notes the entire way and a spinner. :/
[Hard]
00:07:364 (3,1) - Check your spacing here. The .5x section messes with distance snap.
The map itself is fine, but the first half up to the kiai felt kind of boring. It's just mostly a constant eighth note stream with little rhythmic variety. Try to make it work with the music more and this map would benefit greatly for it. :D
[yk's Insane]
01:26:697 (10) - This arrow is facing in a weird direction, if you want to fix it.
Nice~
Taiko looks fine too.
Call me back~
