Nah sorry for waiting so long.
[6K Udon]
00:04:497 (4497|1,4881|2,5266|5) - These LNs kinda lined up in an awkward way imo , I think you can have a better structure by trying
http://puu.sh/Adf35/6208c10907.png instead. (Starting from 00:03:728 - )
00:08:599 (8599|4,8599|3) - Better move the LN to col 2 and the note to col 6. although you don't seem to really follow the pitch too much, but moving the LN to col 2 will resulting in more better expression towards the synth, which i don't think will hurt the overall pattern either.
00:33:728 (33728|3,33984|2,34369|3) - a bit more subjective, but you can basically do reversal pattern like
http://puu.sh/Adfej/d8b299ca6e.png that actually give more flow towards the progression changes of the song.
00:46:805 (46805|4,46805|3) - I think you can switch column between these notes here, overall it provides more structure with the pattern at 00:46:035 (46035|5,46292|0,47061|0,47317|5) -
00:52:958 (52958|2,53087|5,53215|4,53215|3) - Felt kinda awkward hitting these somehow with how the 1/2 LN connected with the 1/4 LN there, i will try
http://puu.sh/Adfv9/7f40f52d8a.png instead. (starting from 00:52:317 - )
00:54:112 (54112|4,54240|2) - Switch column between these notes here to make the overall structure in this section becomes more apparent.
01:03:856 (63856|1,63984|0,64112|1) - This felt really cramped somehow, you can move 01:03:984 (63984|0,64112|1) - to col 3 and col 1 instead to make the pattern has more space.
01:16:676 (76676|3,76933|3) - I'm not sure if making this jack is part of your intention, but it makes the pattern felt forced when there's also 01:15:971 (75971|3,76228|3) - present from 1/8 before, i recommend move 01:16:933 (76933|3) - to col 1.
[4K Poco]
00:11:548 (11548|0) - making this as the same column as 00:11:933 (11933|0,12317|0) - resulting in the latter jack less emphasized there, I will suggest you to switch column between 00:11:548 (11548|0,11676|2) - instead.
00:34:240 (34240|2) - Not sure why this LN exist in this difficulty but not in 6K Udon, since it seems awkward to make differences in that area.
00:47:381 (47381|3,47446|2) - It's actually alright if you switch column between these notes, if you worry about 1/4 jack, you also did that in 00:49:689 (49689|1,49753|2,49881|2) -
00:55:138 (55138|1,55266|2,55394|3,55522|1,55651|2,55779|3,55907|1,56035|2,56163|3) - I think this kinda repeating too much isn't it? I will suggest
http://puu.sh/Adg19/ff08d2c119.png for more differentiation (starting from 00:55:138 - )
[6K Hard]
00:26:035 - I'm not sure gap between 1/2 LN to 1/8 LN , but i will let you decide here, i won't object with either choices as long as you really think it's alright.
00:34:240 (34240|1,34369|2,34753|0,34881|1,35010|2) - Kinda too bias here, i will suggest
http://puu.sh/AdgjD/5cc24b5109.png (starting from 00:34:753 - )
00:55:266 (55266|0,55394|1) - I will suggest to switch column between these notes here for 2 reason: 1. separate 2 distinct vocal between 00:55:266 (55266|0,55394|1) - and 00:55:522 (55522|2,55651|3) - , 2. to make it have linearity with pattern at 00:55:138 (55138|5,55266|4,55266|3) -
01:13:215 (73215|4,73343|3) - I do think switch column here also okay, so you don't really stucked with too many of 01:12:317 (72317|4,72446|3,72702|4,72830|3,73599|5,73728|4) -
[4K Hard]
00:26:035 - Same as 6K Hard, I will let you give final decision regarding this one.
00:40:907 - Kinda suggestion, i think you can make it like
http://puu.sh/AdgDF/4aa8aae242.png so the pattern isn't going to left direction too much.
01:03:215 (63215|2,63343|1,63471|0,63599|1,63728|2,63856|1) - The rotation here makes the overall pattern felt more cramped than what it should be, try
http://puu.sh/Adh2u/5d321d5c71.png01:17:317 (77317|0,77446|1,77702|0,77830|1,78087|0,78215|1,78471|0,78599|1) - nah if this doesn't really emphasize any instrument, having them same pattern really odds here, I will recommend
http://puu.sh/Adhdd/e8ebcd27a8.png[6K Normal]
00:47:317 - Personally will do
http://puu.sh/Adhk4/344f79afbc.png to make it neater in lower difficulty.
01:07:702 - I recommend to change the pattern direction here, something like
http://puu.sh/Adhrs/88f0db3311.png will do. (starting from 01:07:317 - )
01:28:215 (88215|2,88343|1) - Try switch column between these notes for better aesthetic there.
[4K Normal]
00:09:881 - Not sure if you intentioned to not use LN here, but it's inconsistent with the section at 00:18:087 -
00:33:215 (33215|1,33599|2,33984|3,34240|1,34753|2,35010|3,35266|1,35779|2,36292|3) - Same LN pattern here doesn't make sense imo because there isn't any instrument that accentuate the same pattern usage here. I will suggest
http://puu.sh/AdhBO/6440668153.png instead.
I think easy is alright, overall decent map here.
Call me back if you done.
