M4M from my queue.
Easy
00:07:623 (2) - The slider shape for this is weird looking at the white ticks, but the main reason I'm pointing this out is because you could angle it better so that it directly faces the next note instead of slightly away.
00:19:584 (2,1) - Blanket for this is slightly uneven.
00:22:721 (2) - Curve can be improved on this for a smoother blanket.
00:32:721 (2) - You could improve this shape, the curves are both uneven.
00:49:388 (4,1) - The spacing between this is larger compared to the spacing throughout the map.
01:10:564 (1) - Curve on this is uneven, forming an uneven blanket.
01:29:192 (3,4) - Blanket with these looks slightly uneven as well.
01:30:956 (1,2,3) - DS looks uneven.
01:36:446 (4) - You could make a better curve for a more even blanket.
01:57:427 (2,1) - Overlap with these look bad, I would adjust the slider shape in (1).
02:05:466 (1) - Uneven curve provides an uneven blanket.
02:15:858 (2,3) - Uneven blanket.
03:01:152 (4) - I would adjust this curve so that it's symmetrical with the blanket at (3).
03:47:623 (2) - I would change this slider shape to something else, it doesn't really look too good and the blanket it forms with the next note is uneven.
03:59:388 (2,1) - Uneven blanket.
04:04:682 (1,2) - ^
04:36:250 (1,2,3,4) - Maybe use sliders for these? The rhythm may be hard to catch for a beginner.
Normal
00:03:701 (2,1) - Slightly uneven blanket.
00:38:995 (1) - Curve on this is really weird, I would adjust it so that you can form an even blanket with the slider before this.
01:12:721 (2,1) - Blanket looks slightly uneven.
01:37:231 (1) You could curve this slightly less in order to blanket with the previous slider.
02:01:544 (3,1) - Slightly uneven blanket.
02:05:074 (3,1) - Noticeably uneven blanket.
02:30:564 (2) - You could adjust the bottom of this shape with a curve that blankets with the upcoming note.
02:39:192 (4,1) - Uneven blanket.
02:40:564 (2) - Adjust the curve for a more better blanket.
03:34:878 (1,2,3,4) - Equilateral triangle here?
03:57:623 (3) - Tilt this so it faced the next slider more? It's more comfortable for beginners.
04:36:250 - Not a fan with the pattern you have with these last remaining notes. You could probably create a much more creative shape with these, such as a star.
Hard
00:09:780 (2,3) - You could stack these to stay consistent with the stacking pattern you have in this section.
00:10:760 (5) - The tail of this slider isn't perfectly stacked with the (1) in this combo.
00:20:564 (2) - Improve the curve on this for an even blanket.
00:42:133 (4) - You could create a more symmetrical shape with this slider. The curves on both ends of this slider are uneven.
00:43:897 (1,2) - Uneven blanket.
00:46:250 (7) - Improve the curve for a more even blanket.
00:50:172 (1) - ^
00:51:152 (4) - ^
00:52:721 (5) - I know that your intention is to make this more readable, but it looks really weird with this note nearly overlapping the (2), providing an uneven shape. I don't think players will have difficulty reading a perfect stack.
00:55:858 (1,2) - Make the slope of these more even.
01:02:329 (4,5,1) - Blanket is uneven if you look at the approach circles.
01:10:564 (1,2,3,4,5) - I would adjust this over the y-axis for a mirror effect and for symmetry.
01:21:152 (4) - Adjust the curve more evenly.
01:28:799 (3) - Smooth the curve for an even blanket.
01:43:505 - Add a note here for the finish?
01:59:192 (1) - Curve on this looks slightly too sharp towards the end, lessen it for an even blanket.
02:09:192 (3) - Lessen the curve for an even blanket.
02:11:741 (1) - You could create a better curve towards the end of this slider for blanket.
02:15:466 (2) - Make this the same slider shape as (3) for a symmetrical look and so that this slider can form an even blanket with the previous slider.
02:20:956 (3) - Position this better for an even blanket with the (1) and (2) in the next combo? Either that, or adjust the (2) so that it forms a more even blanket.
02:30:564 (1) - Personally, I find this slider shape to be rather boring, I would make something more interesting.
02:48:995 (5) - The curve on this is really weird which creates an uneven blanket with the (4). I would adjust it so that both the sliders are symmetrical.
02:58:211 (5) - You could tilt this this to create a blanket with the (4), it looks uneven.
03:13:113 (1,2,3,4,5) - The shape looks irregular and random, you could create a star out of this.
03:25:270 (1) - You could tilt this slider to form a blanket with the (2) in the previous combo.
03:29:976 - This spinner seems very random, I would remove it and go with the current rhythm you had previously.
03:32:329 (1) - This slider doesn't sound right in the song at all, I would remove it and do the suggestion I had above. ^
03:33:701 (2) - Curve to form a blanket with the (1)?
03:34:486 (4) - Similar to the above.
03:59:780 (1,2) - Uneven blanket.
04:01:152 (5) - Rotate slightly for better flow towards the next note?
04:02:133 (2,3) - Uneven blanket.
04:15:466 (3) - You could move this a little bit to form a better blanket with the head of (2) in the previous combo.
04:18:211 (3) - CTRL + G flows better to me because it leads into the curve better on the slider afterwards.
Insane
00:21:741 (2) - CTRL + G flows better to me.
00:54:682 (7) - You could place this more evenly between the two notes.
01:08:995 (1,1) - I think a perfect stack with these looks better.
01:23:309 (2,3,4,5,6,7) - Not sure why the spacing is the largest here, this would fit in better at 01:24:878
01:27:427 (5) - I would add NC here since you did it to a part this is similar to 00:18:407 (1)
01:31:348 (2) - You could adjust this to form a blanket with the previous slider.
01:33:309 (4,1) - I don't agree with how you spaced this because the song doesn't really emphasize it. I would move it closer. Maybe you heard something in the song to do this, but I don't really think it fits in.
01:38:995 (2,3,4,5,6,7) - Spacing is too large in my opinion. The song isn't as emphasized here as in the other similar sections.
01:43:505 (1,2) - You could make a more even blanket with this.
02:05:467 (1,2) - Curve is too sharp on (1) making the blanket uneven.
02:14:878 (1) - Smooth the curve on this for an even blanket with the (3).
02:26:643 (1) - Lessen the curve on this to form a blanket. If you do this, then make the (2) the same shape as this slider afterwards.
02:49:584 (2,3,4,5,6,7,8) - Not sure why you're decreasing the spacing here, it's the most emphasized compared to the section previously.
02:52:133 (5) - You could probably add a NC here since you do it for similar portions.
03:30:956 (3,4,5,6) - I don't think these kicksliders are necessary here.
03:36:839 - I think a note here would fit in well.
03:51:741 (5) - NC with this?
04:04:878 (2,3,4,5,6,7,8) - Same thing with this, I'm not sure why you decrease the spacing here even though it's the most emphasized.
04:07:427 (5) - NC?
04:16:446 (4,5) - The spacing between these is too large and seems random. I would adjust this.
Kisu~!
Without me looking at this yet, I'm not really sure why a nearly 5.7 star difficulty is really needed for this song. It seems rather forced. With that being said, I'm not going to mention anything about the spacing in the mod for this particular difficulty.
00:06:250 (1,2) - Uneven blanket.
00:37:623 (1,2) - You could adjust the (2) to form a better blanket with the (1).
00:38:995 (1) - The curve towards the end of this slider doesn't really look that good, I would adjust it to look better and possibly form a blanket.
01:27:427 (5) - Not sure if you want these here at all, but you could add NC's to this note similar to the other difficulties. I've mentioned this before a lot, so if you decide not to do this then just ignore these.
02:07:623 (1) - I think you meant to end this repeat slider on the white tick, not the blue one.
02:56:839 (5,1) - Better blanket with this.
03:06:643 (1) - This is spaced much closer compared to 01:41:937 (1)
03:26:839 (1,2) - This sounds really weird rhythmically, but I guess it works in a way with the guitar.
03:51:348 (1,2,3,4,5) - Even though I wasn't going to mention anything spacing related, I wanted to point this stream out because I think you should stick with the regular DS you have for all of these sections, such as 01:11:348. This doesn't sound any different compared to the other ones, so I would just make it the same.
03:58:015 (7,1) - Neater blanket here.
04:07:035 (1,2,3,4,5) - Similar to what I mentioned with the stream.
04:14:094 (1,2) - More even blanket, possibly with the other notes in the previous combos as well, but it would ruin the stacking patterns you use.
In general, I didn't point out every single thing aesthetics-wise because it would have made this mod much longer than it should be. Some things need polishing a little bit still from Easy-Insane. The Extra difficulty doesn't really need too much polishing, but you should be prepared for the future with this difficulty because a lot of people are going to question the spacing if you're intending to rank this.
Good luck with this mapset!
