sorry for really late reply
General
--kiai times are different
Insane
00:11:179 (2,3,4) - I just don't like patterns like this that much, because the notes are both stacked but have different rhythms. If you want to keep it, it's fine, since I read it perfectly fine.
00:50:783 - you can add a note here or start the spinner here.
01:25:244 - if you are not going to map this break (which I feel should be mapped, but that's just me), then you should at least add a note here imo. I say this because really the only reason you have this break I would assume is because of the bass and drumming stuff in the background, which stops right here, and it just makes sense to end with it (but i know you left that note out to follow the melody)
01:41:532 (8,1) - this is just really awkward to play ._.
01:42:903 - add note
02:13:250 (1,1,1,1) - maybe it's just me, but i don't really see a need to put new combos on all of these, and it's not like this is a draining sections or something
02:15:307 (4) - new combo
02:47:711 (1,2,3,4) - quite hard to read imo.
02:57:140 (1,2) - these two notes look a little notes since they aren't aligned with the rest of the stream
02:59:541 - If I was mapping this I would add a note here, but that's just my opinion. feel free to ignore this.
03:17:371 (3,4,1) - I'm a little hesitant to do this, tho just a little. I say this just because this is the first you do this and previously you've just had constant 1/2 ticks notes and stuff. To me, it isn't that intuitively obvious that this is anti-spaced, but I've heard this song repeat enough times to realize something.
03:26:630 (6) - new combo?
03:37:259 (1,1,1) - useless imo
03:42:231 - end spinner here? I would use a soft hitsound with no finish ( and 5% volume )
Hard
--hmm, there's quite a lot of continuous 1/2 ticks notes. Seems a little hard for a hard, but ok.
00:34:496 (3) - not the most intuitive repeat slider I've seen... but it's not a huge deal if you don't change it
00:49:583 (1) - hmm...? This ends in a different place than insane. I would rather you end these spinners in the same place.
01:25:244 (5) - new combo
01:31:416 (5) - new combo?
03:26:630 (5) - ^?
Normal
--SV vs. spacing ratio is almost 2:1 ._. This can make a lot of correctly spaced notes quite confusing especially for beginners.
--I would also avoid using as many red ticks as you did in this difficulty. I wouldn't consider this a normal at all. It's definitely a lot harder than one, especially at the end.
00:39:296 (1,1,1) - ..i don't see a need for this?
00:49:584 (1) - same as hard.
02:44:797 (1,1) - i don't see a point
Easy
00:12:550 (2,1,2) - weird spacing.
00:18:037 (2,1) - spacing..
00:40:668 (2,1) - yes it's a tiny spacing change, but it just looks more clean if you spaced them correctly..
02:53:712 - add note?
... and then Full Submit.
I play your other three ranked maps really´withh a lot of fun
