Hard difficulty Got 61% Accuracy when I played it (with no fail)
I think you have to be more consistent with the spacing between the notes especially on hard difficulty throughout the whole map.
It could also be a good idea to avoid blocking/hiding notes with sliders too much.
Noticed that you use one BPM on the hard difficulty and another on the insane, shouldnt they be the same?
(Might sound as if I complain alot but some parts of the map are quite nice)
00:02:087 (3) - It looks better if this slider dont block notes before and after. It will be easier to read the map too.
00:10:114 (4) - Same -"-
00:08:168 (5) - -"-
00:02:087 (3) - This slider start on red and end on red. Its on yellow to yellow at the moment.
00:24:060 (9) - There is no vocal or instrument playing here so I think it will sound better if there is no note here at all.
00:35:331 (8) - Another slider from yellow to yellow. You could place it on blue to blue.
00:37:196 (3) - Would add a note here.
00:52:763 (9) - Here
00:52:925 (10) - And here
00:54:871 (5,6) - Delete these two
00:54:871 (5) - and replace them with a note here.
00:56:331 (3,4) - Make the sliders shorter and let them end on red. When you make the first slider shorter you can let the second slider start on blue where the first one end now.
Alternative version, you could keep the first slider as it is if you delete the second one and replace it with one single note here 00:57:141 (4) - or you could move the old slider here. Anything works as long as you change it.
01:25:520 (6) - There is pure silence here, sounds better to remove the note.
01:25:844 - The instrument start here not on the blue. I suggest you use a slider from red to red.
01:24:871 (5) - This part sound suspicious to me as well. Try delete the slider and...
01:25:196 (5) - Place a short slider here instead from red to blue.
Insane difficulty
00:07:277 (3) - I wrote it earlier, you have to be more consistent with the distance between notes. This is just an example of something unreadable.
00:08:979 (1,2,3,4,5) - Same.
00:10:682 (9) - You need to look over this slider. You could use a shorter slider from white to white instead (00:10:925 (9) - )
00:14:087 (1) - This note should be on the red, not blue.
00:14:655 (3) - This slider end on white not blue.
00:15:304 (4) - Sounds wrong with a note here, silence.
00:16:033 (6) - This one cant be on blue but you can move it to white.
00:16:763 (1,2) - Just replace the single note (2) and make the slider longer instead.
00:19:763 (2) - Similar thing here, delete this note and
00:19:844 (2) - Move the next slider so it start and end on red.
00:24:141 (10) - Cant have this note here but
00:24:223 (10) - You can move it here to the white one instead.
00:25:033 (4,5,6) - Have to do something about these sliders. You could...
00:25:033 (4) - Use a reversed slider that start on red, goes to red and then end on red. She sing on red so anything you put there cant be wrong.
00:28:195 (5,6) - Delete these two and
00:28:277 (5) - replace them with a slider that start on red or you can
00:28:195 (5,6,7,8) - delete them all and make a slider 00:28:277 (5) - to here 00:28:763 - (its from red to white).
00:29:412 (8,9) - There is silence here.
00:29:736 (1,2) - Same thing as earlier, remove the single note and make the slider longer instead.
00:30:304 (2) - She start singing on the red not blue. (slider from red to red works).
00:34:033 (6) - No note here it dont sound ok.
00:34:601 (7) - Same here.
00:34:114 (6) - Instead you can make this slider longer so it end on White
00:34:763 (7) - This slider should be as long as the last one (6)
00:35:412 (8) - Delete this slider and replace it with a single note.
00:36:223 (1,2,3,4,1,2,3,4,5,6,7) - If you decided to take your time and try all the above you might want to change whole this part too.
00:40:520 (1,2) - These two are placed on blue but you want them on
00:40:439 (1,2) - white and red instead.
00:41:412 (6,7,1,2,3,4) - You need to look over whole this part too.
00:45:304 (1,2,3,4,5,6) - And this one.
00:47:736 (3) - This slider end on white not on blue.
00:49:033 (7) - Same here, it end on white not on blue.
00:50:412 (3,4) - Need to change this too.
00:52:358 (8,9) - These cant be on blue but you can place them on red.
00:53:087 (1,2,3,4,5,6,7,1,2,3,4,5) - Need to change this.
00:58:195 (4) - She start singing on the red so I suggest you start the slider there instead of on the blue after.
Hope this didnt get too cumbersome, it probably did.
