Good job~ ^^
Just a few suggestions:
[Overall]
Perhaps add anime japanese to the tags.
[Sweet]
Personally this can be a bit simpler for an easier difficulty. :3
00:09:610 (1) - Add a finish?
00:17:110 (6) - ^ (at end?)
00:20:610 (1) - Consider replacing with two sliders. One from where (1) started to the repeat, and another starting from the large white tick next to it and ending where (1) used to end.
00:24:610 (7) - Finish on the end?
00:29:610 (1,2,3,4) - Perhaps make these a bit quieter?
00:31:110 (2, 3) - 1/2 beat long?
00:36:610 (7) - Align with (6)?
00:41:610 (1) - Finish at the beginning?
00:45:610 (2) - 1 beat long?
00:53:610 (5) - Finish?
00:57:610 (4) - ^
01:01:610 (x) - Add a note here, start spinner immediately after?
01:05:610 (4) - Finish?
01:13:110 (2) - ^
01:33:610 (1) - ^ (Beginning)
01:37:610 (1) - ^ (Beginning)
01:45:610 (1,2,3) - Align with (7)?
01:45:610 (1) - Finish (Beginning)?
01:47:610 (4) - Align with (5,6)
01:49:110 (1,2,3,4,5,6,7,8,9) - Long 1/2 beat stream for an easier difficulty, is it not?
01:53:610 (1) - Finish?
01:54:110 (1) - New combo?
01:54:610 (6) - (7) should probably start here.
01:58:610 (3,4) - (4) ^
02:02:610 (3,4) - ^ And etc. If you change one, you should change all of them. If you keep them, keep it for all of them.
02:01:610 (4) - Finish? (etc. I think you get the idea.)
02:17:360 (4,5) - Uneven
02:18:860 (1) - Move to next white tick.
03:21:110 (3,4,5,6) - Personally, I think this rhythm works better.
[Relax]
(Consider renaming "relaxed")
Add some hitsounds in the places named above.
00:53:360 (6) - Make (4,5,6) a line?
03:21:860 (7) - (5,6,7) ^
[Rough]
00:14:110 (2,3,4) - Align?
01:18:110 (1) - Consider:
02:21:485 (1) - Consider:
03:09:360 (1) - Add a note where the spinner starts and one more on the next white tick, start spinner after?
03:25:860 (1) - See 02:21:485
