Modding as requested!
[General]
Lower the Lead-in time to 1 or 1.5, 3 is way to long of a wait.
[Insane]
00:03:144 (4,5,6) - This is 1/6 not 1/4. You should change this to a 1/6 slider or even a stack if you want.
00:06:444 (4,5) - ^
00:09:644 (5,6) - ^
00:38:244 (1) - I would delete this note. The constant stream sounds ugly and floods the music with those custom hitsounds, and if you slow down the song you'll hear no beat there connecting the two streams. (If you do this make sure you move the new combo to 00:38:344 (2) - )
00:39:544 (1,2,3,4,5,6,7,8,9) - Honestly this would be better with a slider. But if you want to keep the stream it should start on 00:39:944 (5) - because that's where it actually makes sense musically. 00:39:544 (1,2,3,4) - Have no music to represent a stream.
01:14:944 (4) - Now I didn't have a problem with these sliders when you did them previously but this one isn't working so well. After it ends there is an awkward pause that leaves the player unsure of whats going to happen next. (Unlike before when these holds lead right into another note) If you swap this for a slider that turns up to the next stream it would play better. Also you could make the slider .50, it would fit very well.
01:18:944 (1,2) - Try making these note stacks instead. These can get easily mistaken for a slider-stream jump.
01:38:819 - add a note here? The stop kills your flow and momentum.
01:39:569 (4) - Reverse this? Could make a nice jump into the next combo.
01:42:944 (7) - New combo? Represents the speedup slider and a combo fits here anyways with the downbeat.
01:54:944 (1) - Touching HP bar. >_>
[Beren's Hard]
Unsnapped inherited (green) timing point(s) at: 01:53:544
00:01:944 (1) - Delete this note to keep consistent with the Insane. Having a note 1/2 away from the end of a spinner is too close for a Hard anyways.
00:29:944 (1) - This needs to be 1/2, the slider tail should land on the white tick to stay on beat. This is also too hard to understand for a hard diff.
00:36:344 (1) - ^
01:06:744 (3,4,5,6,7) - This does not fit the music at all. Listen closely and you'll hear the beat goes:
http://puu.sh/1jK4p You're skipping over the blue tick with a slider and completely missing the rhythm of the music. This applies for every other time you do this: 01:08:344 (3,4,5,6) - , 01:10:144 (3,4,5,6,7,1) -
01:11:144 (2) - Again you've got the wrong rhythm here.
01:12:544 (1) - Why did you stop using the custom hitsound kick here? This part sounds super empty without it.
02:16:801 (1,2,3,4,1,2,3) - You've also got the rhythm here completely wrong. Please follow the melody's rhythm, this will cause too much confusion.
02:23:658 (1,2,3,4) - ^
That's all. No issues with the Normal and Easy. Good taiko as always aabc!
Fix this up and i'll give you your bubble back.
