02:13:035 to 03:24:349 FastYoshi
03:24:349 to 04:53:492 Hydria
04:53:492 to end Staravia

00:54:006 (54006|2) - this note doesn't play anything, remove it.
01:30:520 (90520|2) - maybe change this single into a half sized LN, as the same dub sound plays again just without all the drums.
01:46:977 (106977|2) - I feel like this part with the single's and doubles needs to be re-worked slightly, most the notes don't match up with anything, I assume you're mapping the crackly sound that builds up in the background along with the laser sounds, but the crackly bit starts off slowly and then gets faster and faster whereas your single notes stay the same speed.
02:10:292 (130292|1) - no need for this to be a triple as it's the same sound as the doubles. remove the note on lane 4.
03:10:120 (190120|3) - should start at 03:10:035
03:10:806 (190806|0) - should start at 03:10:892
03:24:349 (204349|0) - maybe move this double to lane 3 and 4, not a huge deal though.
03:43:549 (223549|1) - (The note in lane 2) Move to lane 3. smoother to play.
03:49:035 (229035|1) - feel like this should be a double, add a note in lane 3.
04:56:235 (296235|1) - add a single note in lane one next to the LN for the sound of the choir(?).
04:58:977 (298977|2) - ^ but lane 4
05:01:720 (301720|1) - ^ lane 1
05:04:463 (304463|2) - ^ lane 2
05:07:206 (307206|1) - ^ lane 1
05:09:949 (309949|2) - ^ lane 4
05:12:692 (312692|1) - ^ lane 1
- the timing point you have at 5:59:320 increases the hit sound volume to 70%, I think this is a bit much, I know it's there to emphasize the big prominent part but the hit sounds become distracting when they're that loud, especially if you start missing notes etc. I'd say make all the volumes 5 - 10% less and turn down this 70% to 50% if you still want to keep it being louder. (But personally I feel the hit sounds are distracting from the song overall)

are you going to make another keymode diff? if not remove the "4k" in the diff name

Nysrogh

00:52:463 - according to your patterns, this should be a double

FastYoshi

02:33:606 - reduce the SV such that the LN end is readable

Hydria

04:09:606 - pretty darn boring considering it's nonstop repetition of a pattern for 50 seconds straight

Staravia

05:58:892 (358892|0,358977|0) - minijack seems forced and out of nowhere, looks unnecessary as well
