General
You need a difficulty that is below 3 star rating, so I suggest you start on the Easy difficulty
You have the tags "Tatenashi Sarashiki Infinite stratos season two True Blue Traveler anime pop" on the Hard difficulty only, which is an issue. You don't need these tags as well, because they are already in the data, so you should remove them from the Hard difficulty
Normal
You need constant spacing between notes
examples that are not following this rule are 00:46:438 (1,1) - 00:52:438 (5,6) - and 01:14:674 (6,7) -
00:03:731 (3) - object end is not snapped
00:45:717 (4) - not snapped
00:03:378 (2,3) - slider before circle
00:07:085 (2) - slider starts at 00:07:261
00:07:967 (3) - slider starts at 00:08:320
00:08:850 (1) - inappropriate and not nice and you probably cannot have this here, change the shape of the slider and also end it at 00:10:614
Have a spinner after that slider and end the spinner at 00:11:850
00:35:850 (3,4) - possibly shift them so that 4 isn't covered completely
00:51:026 (1) - remove NC (New Combo), NC at 00:51:379 (2) -
00:39:732 - add a note
00:42:909 (7) - NC
00:43:261 (1) - remove NC
01:12:908 (3) - slowdown slider not necessary, could confuse people
Normal is not complete, continue to map till the end
Hard
You really really really should not put so so many sliders starting on a red line, it is not good for playing or rhythm
00:04:579 (5) - object not snapped
00:17:674 (1) - just replace it with a note at 00:17:850
00:20:320 - add a note
01:01:968 (12) - 1/4 beat repeat slider redundant, only the 1/2 beats are required for the music here
01:08:497 (1,2,3,4,5,6) - too cramped, space things out
01:12:555 - important beat here, why leave it out?
01:17:320 - ^
01:17:850 - ^ again you just breezed past it with a slider that isn't on anything important
01:18:379 - ^
01:18:732 - ^
01:19:262 (9) - 2x slider velocity is definitely not needed and does not fit. Remove it.
Hard is not complete, continue to map till the end
Insane
Again, do not have too many sliders starting on red lines
00:05:497 (1) - remove the repeat, slider still ends at 00:05:850
00:38:144 (5,6,7) - why are they suddenly so close to each other as compared to the rest, space them out equally
00:41:408 - add a note
00:45:732 - important beat here, why breeze pass it
00:46:967 (5) - slider ends at 00:47:144
00:48:203 - important beat here, why go past it
00:54:203 - ^
01:12:555 (1) - slider body cannot be seen, quite unrankable
01:16:438 - imprtant beat, why skip it
01:16:791 - ^
01:17:144 (1) - why start there, beat is at 01:17:320
01:17:673 (2) - why start there, beat is at 01:17:850
01:18:203 (3) - why start there, beat is at 01:18:379 and 01:18:732
Insane is not complete, continue to map till the end
Infinite
Snap back your uninherited points
00:32:850 - unforseen and very random sudden 2x slider velocity change. Remove the velocity change, this is a rankability issue
00:45:555 (8) - slider end at 00:45:732
00:46:703 (2,3,4,5,6,7,8,9,10,11) - again overmapping here. Beats are at 00:46:791 - 00:46:967 - 00:47:144 and 00:47:497
00:47:938 (2,3,4,5,6,7,8,9,10,11) - ^ same thing, overmapping
00:55:791 (2) - remove
00:55:967 (3) - shift to 00:55:879
01:02:673 - again the slider velocity here is ridiculous, reduce it
01:15:379 (10,11,12) - there is only 1 holding of vocal here, and you place a 1/4 beat rhythm of sliders here, overmapped.
01:19:085 (1) - shift to 01:19:261 and add a note at 01:19:085
Infinite is not complete, map until the end.
Decreasing circle size and making insane slider velocity is not the way to go to increase the level of difficulty of a map. A lot of work is needed for the mapset as of right now.
