Easy:
-- I think the slide velocity is too fast, does that affect taiko?
Some slight spacing inconsistencies here (what AIMod doesn't seem to mention :/), slight jumps between combo's which I wouldn't recommend on an Easy e.g. 00:04:618 (3,4,1) - and 00:07:255 (5,6,1) - and 00:12:530 (5,6) - but they are manageable so it's up to you whether you change it.
00:23:739 (4) - Spacing error, anti jump...
00:27:035 (6,1) - Spacing... intentional?
00:30:332 (1) - Could move this away from 00:29:013 (5) - slightly.
Normal:
00:09:894 (3,4) - Slight spacing error.
02:11:872 (6,7) - ^
Plus the one's Zekira mentioned. Good overall
Hard:
-- The spacing here is all over, I sort of get the pattern x0.8 then x1.0 for slight jumps but imo the slight jumps make no sense and throw off the rest of the spacing examples below:
-- I'd recommend using x0.9 or higher here instead of x0.8 so the circles don't overlap.
00:08:079 (7,1) - Why the slight jump?
00:10:057 (4,5) - ^
00:10:717 (7,1) - Huge jump, but considering the other small jumps its inconsistent spacing.
00:13:849 (9,1) - Anti-jump...
00:17:145 (1,2,3) - x1.1 jumps then...
00:18:794 (8,1) - x1.2 then...
00:20:112 (5,6) - x0.9 then...
00:20:937 (9,1) - x1.5 then etc etc. I use the distance snap as an indication of how much the spacing fluctuates making the map harder to read.
01:48:134 (1,2,3,4,5,6,7) - 01:48:794 (5,6,7) - are slightly wider than the others.
01:49:453 (1,2,3,4,5,6,7) - Seems to progressive increase slightly in spacing, the slight changes making it harder to read.
Yeah that's the main problem imo the spacing is hard to read, I'm not sure if this is due to manual snapping or accumulated edits over time but it should probably be fixed, also increase the distance between circles so it looks less messy in game?
So yeah, popping the proto bubble until the spacing on Hard is fixed as LKs said define a spacing standard I think it will help the map

EDIT: Already popped for an unsnapped note,
seriously the spacing is more important >_>
