[General]
Boundary case for me but better switch on the flashy warning... Since you have several seconds before the song start, it won't hurt if you have a warning there.
[Normal]
00:51:489 - spinners might be a bit short. How about putting a single note here and start spinner 1/2 later?
03:24:266 (6) - whistle as you've done in hard and refer to music
03:34:544 (2,3,4) - [Nazi] minor fix so that (2,3) curves in the more similar way

generally spinners are a bit short and the coming note is quite close but I consider as ok because the song is qutie slow. Only pointed out one spinner because it's the shortest and has room to extend it.
Fix them and call me back.
