Yo!
[General]
The soft-hitnormal sounds feel far far too soft in comparison to the music and the custom hitsound used. It makes it feel like there are gaps in your hitsounding -everywhere- I recommend you rethink how you used hitsounds in this and adjust accordingly.
[Easy]
00:05:654 (1,2) - The problem with using such a slow slider velocity combined with very low distance snap is that spacing like this is very difficult to read. You -have- to look at the approach circle instead of being able to intuit the spacing. I really recommend you tone this part down, especially since this is an Easy. Also remove new combo here.
00:08:551 (2,3) - Same thing going on with the spacing here. It looks nice, but the rhythm is difficult to read when everything is this close together.
00:10:426 (3) - Remove new combo
00:31:733 (3) - New combo
00:32:926 (1) - remove new combo
00:39:404 (3) - I really don't recommend using these types of short sliders in an Easy - especially when you have notes so soon after them.
00:47:074 (1) - remove new combo
01:48:438 (1,2) - This rhythm is really awkward. Maybe try something like this?

01:57:983 (1) - Remove new combo
[Hard]
02:00:029 (1) - Remove new combo
02:16:563 (6,7) - I wish you put these soft whistle sounds in the Normal and Easy.
02:22:017 - I really wanted a hit object here to click
02:22:699 (1) - It also leads to this pattern being misplaced since the new combo should start at 02:23:040 (2) - or 02:23:551 -
02:27:472 (1) - Remove new combo
02:31:733 (1) - This part plays weird since the emphasis is placed on the wrong beats. It should be more like this:

[Taiko]
00:12:642 - Kiai really needed here? It's probably best to leave it at the chorus'
00:38:040 (17,18,19) - ddk sounds better
[Insane]
00:09:063 (2) - Repeat arrow is being covered by the hitburst from 00:07:870 (2) -
00:10:512 (5) - Delete
You know, there are a lot of unnecessary 1/4 rhythms throughout this entire map. Look through and see what you can find. Try to have some musical justification for having them. Right now most of them are there just to add difficulty which really doesn't represent the music well.
Also check your new combo use. Try to line it up with how you used them in the Hard and Normal difficulties. Right now they're inconsistent and kinda weird.
Don't forget to address Xgors musings as well!
