General:
-- You need an easier difficulty.
-- Remove "Arashi" from tags.
-- Video offset seems a little off but its hard to tell...
-- Remove the silver combo color is clashes with the video.
-- I didn't test your timing thoroughly but it seems ok.
Normal:
-- Preview Point?
00:49:594 (4) - Spacing is too far.
01:04:451 (3) - Spacing, too far.
01:39:880 (5) - Too close.
01:42:165 (10) - Too close
01:46:451 (6) - Too far.
03:35:451 (1,2,3,4) - Jumps in normal.
Spacing changes and jumps are okay, but since this is your easiest difficulty I think they should be fixed, if you make an Easy then thee aren't really a problem.
Insane:
-- Reduce OD by 1?
01:04:880 (7,8,9,10) - Stack?
02:22:451 (5) - Too far.
02:23:308 (x) - Note?
02:52:023 (3,4,5,6,7,8) - Reduce the spacing between these.
02:54:308 (1,2,3,4,5,6) - ^
03:07:451 (7,8) - Stack?
The spacing is hard to follow at times, you might want to consider using AIMod as a reference. Also consider reducing the spacing on your streams to make them easier to hit.
Well there's a few other things I could probably pick up on but this will do for now, make sure to add an Easy
