Ohai. I'm from popner's queue.
Mochi's Easy
00:23:657 (2,3) - I'd prefer an arc pattern here. Put (2) in 180|200 and (3) in 232|140
00:29:282 (3,4) - I don't like this orizontal line... Put (3) in 228|112 and (4) in 180|256 maybe
00:34:595 (2) - Curved is better imo
00:42:720 (1) - This is not perfect, you should remake it with the new algorhythm
00:49:907 (2) - Move to 220|280. It flows better
00:53:970 (3,4) - Why don't you make this pattern symmetrical?
01:00:220 (5) - This is supposed to be in 257|176 to stack with the previous circle
01:05:220 (2,3) - Better this way imo
01:07:720 (2) - Like this?
01:12:563 (4) - Try this, or something.
01:18:345 (1,2,4) - These three sliders are overlapped, please do something to fix them
01:21:157 - Add a note?
01:23:970 (1,2) - Make a blanket? Also, add a repeat to the second slider
Dekaane's Normal
00:11:157 - Add a note, like in Easy
00:22:720 (1,2) - Curved?
00:31:782 (2) - I don't like this slider, it's strange... Try this
01:06:157 (4,1) - Swap NCs. The song says "one, two,three" so it's better to have a combo of three notes lol
01:08:970 (1) - Put the central sliderpointpoint in 188|72
01:25:688 (6) - Replace it with a silenced slider. End it in 01:26:157
Hinely's Hard
00:18:970 (1) - Please try this rhythm, it fits better imo (I'm lazy and i don't want to cut the screenshot lol)
00:22:095 (1) - Something like this is better imo
00:26:938 (2) - Put the final sliderpoint in 220|380
00:29:595 (3) - Final sliderpoint to 320|56 please
00:38:501 (2,3,4) - Stack them properly
00:43:657 (4,5) - This way please
00:55:220 (1,3) - Make them curved... If you know what I mean
01:06:157 (4,1) - Swap NCs
01:12:251 (1) - Convert this into two sliders?
Mochi's Insane
00:16:470 (1,2,3) - Can you move this to the center somehow?
00:21:860 (17) - Streams usually finish on big white ticks... I suggest you to remove this note
00:22:407 (2) - Move to 132|28
00:25:532 - I'd add a note here
00:31:626 (4,5,6,7,8) - It's better this way...
00:38:501 (4,5) - Improve a bit this blanket
00:39:907 (8) - move to 256|60, right in the center
00:40:688 (2,3,4) - What an odd flow... Make something like this. If you don't like my suggestion at least change it in another way!
00:45:610 (7) - Move 1 or 2 grid down
00:50:063 (2) - 416|208 in order to avoid that overlap
00:50:220 (3,4) - Like this?
00:52:399 (9) - 180|28 ?
01:08:657 (4) - This is supposet to be here: 418|192
01:25:688 (1) - Replace it with a silenced slider. End it here: 01:26:157
