Yo, sorry I took so long to get to this.
[General]
02:48:942 - This is a weird place to end the kiai. 02:42:942 - End it here if anything.
[Easy]
00:12:942 (1) - This is too soon after a spinner for an easy difficuty. Maybe end the spinner at 00:11:817 - ?
00:25:692 (1) - This is also too soon. Doesn't seem to be an easy solution here beyond some slight rhythm changes or cutting the spinner really short, and that isn't desireable since it'd be awkwardly short for an easy. See what you can figure out.
00:49:504 (4,5) - maybe to simplify this a little delete 5 and extend the 4 slider to where 5 was.
00:54:192 (1,2,3,4,5) - This string is fairly complex for a beginner level map. Each object that comes up has a different time value to it. See if you can simplify this a little bit.
01:59:067 (2) - An alternate rhythm suggestion here:

[Normal]
00:08:067 (3,5) - I'd remove the finishes on these. They don't fit.
00:25:317 (1) - Way too soon after a spinner for a normal. Try for two beats at this BPM.
00:51:192 (1,2) - I was really wanting this next combo to start in the left left of the screen since that short slider really pushes the flow in that direction. Having it start back at the top was disruptive to an otherwise smooth play.
01:27:192 (2) - I don't understand why this is extended to 01:27:754 - and the spinner starts at 01:28:129 - . Move them back to the white ticks.
02:18:192 (1,2,3) - Move these down and right 2 grids to adjust for stacking.
02:42:942 (1,1) - I prefer the way R a i n did his spinner transition. Check the easy and see if you like it better.
[Taiko]
00:12:379 (3,1,1,1,1) - kddkd
00:15:942 (1,1,1,2,1) - These finishes felt rather inappropriate
00:18:942 (1) - And then you miss a perfect opportunity to add one in.
00:36:379 (1,2,3) - These feel better as k
00:50:254 (2,1,2) - I'm not feeling this rhythm at all considering the music.
00:58:692 (3,4,1,2,1,2,1,2,1,2,1,2,3) - Why? 01:03:192 (1) - This is the best place for a longer stream, and you already took advantage of that. Why this one?
02:18:942 (1) - This kiai section feels so empty. This is supposed to be the big finale of the piece.
[Hard]
02:42:942 (1,1) - I prefer the way R a i n did his spinner transition. Check the easy and see if you like it better.
Otherwise this is pretty nice.
[Lunatic]
00:04:129 (2,3,4) - I'm not a fan of all these 1/4 stacks. They're disingenuous to the music. They're not following anything in the music in any case. They're also all over the map. :/
01:45:754 (6) - The timing of the finish is ever so slightly off. It just feels wrong to me, I guess.
02:13:504 (1,2) - Due to the direction of the jumps from these two sliders, I really wanted to continue that back and forth direction, but instead was confronted by 02:14:254 (1,2) - and felt like the flow was ruined and a great opportunity for a flowy jump pattern was lost. See if you can rearrange this so it remains awesome.
02:42:942 (1,1) - I prefer the way R a i n did his spinner transition. Check the easy and see if you like it better.
03:03:004 (6) - You can barely tell there's a slider there.

The taiko needs a lot of work still. I asked in #taiko for some volunteers to mod this. I don't know if anyone will come, but it's a start. See if you can get it in a better state, then call me back. :3
