Easy:
00:30:738 (4) - Curving up will be a better flow.
00:38:847 (2) - ^
00:39:928 (1) - Curve right for this one.
00:51:279 (2) - Delete Whistle at the end. There isn't in the song.
01:03:171 (2) - Add Whistle will be good.
01:09:117 (3) - Delete Whistle at the start for consistency?
01:13:441 (3) - Add Whistle at the reverse.
01:21:009 (3) - Delete Finish at the start.
01:25:333 (3) - ^
01:23:171 (2) - Start NC here. It will fit the song more..
S.Wing's Normal:
00:01:549 (2) - NC
00:12:630 (4,5) - 1 Grid right
00:24:792 (3,1) - Starting NC at (3) will be better.
00:29:657 (1,2) - Similar above. Start NC at (2)
00:44:792 (1) - Delete Whistle at the reverse.
00:48:036 (3) - Delete Whistle at the start.
01:04:792 (1,2,3) - Instead of this kind of stack, make a new pattern? This is my suggestion..

01:06:414 (4) - NC
01:09:117 (5) - Delete Whistle.
01:12:090 (3) - Imo, deleting this will be better...
01:16:414 (1,2) - Start NC at (2)
01:23:171 (1) - Delete Whistle at the end
01:29:657 (5,1) - Start NC at (5)
01:31:819 (1) - NC
Hard:
00:02:630 (3) - (116,192) will be perfect.
00:04:792 (3) - For this one, I'd prefer to slide up. This way, you can make a better flow, and also imo touching (2) didn't felt well.
00:09:117 (2) - Uhh.. I think you've followed the Finish sound from the song, but I think just making this a Clap will be better.
00:11:549 (3) - 1 Grid right.
00:12:901 (1,2,3,4) - I definitely believe this will fit better as 2 sliders. Here is an alter that I suggest. Well the shapes aren't the best, but this kind of jump/flow will be nice.

00:20:198 (4) - 1 Grid down.
00:28:847 (6,1) - For this kind of rhythm, I suggest you to start a 1/1 slider at 00:28:847. Containing a jump will be better imo.
00:43:576 (2) - Place at (244,324) for a better flow.
00:54:522 (4) - Flow a better flow, doing something like ctrl+G will be better. Consider this pattern?

00:57:090 (2) - 1 Grid left.
00:59:928 (2) - Consider deleting this? In this part, following the piano(?) will be better. Actually, it was quite tough to click this..
01:00:468 (4) - If you adjusted above, make this NC since this is following drums. Also, change this shape by yourself because touching 01:01:549 (1) didn't seem well.
01:13:847 (2) - (233,50) will be nice.
01:18:036 (2) - Add Whistle at the end for consistency. Also delete Clap at the start, regardless of your pattern.. I don't think clap sounds well.
01:18:576 (3) - Delete Clap
01:20:468 (4) - Add Whistle at the start for consistency.
01:24:252 (3) - Delete Whistle for consistency.
01:26:144 (1) - ^
01:35:874 (3) - Delete Clap?
Fine map overall, but I guess this isn't the best. That's all I can say for now :3
