02:01:805 (4,1) - Please check your pattern of the stack at here 00:24:117 (2,3) - ,00:25:992 (4,1) - ,02:08:555 (2,3) - . you made a different pattern of the stack. so i would remove this stack for beginners. If you follow my suggestions, it prevents the player from misreading.

00:15:867 (2) - As you can see here, since you already have the up and down motion from your previous patterns, the transition from this to the next slider almost feels like unnatural jump. so i recommend you to use ctrl + G to this slider.
00:33:680 (1) - Design suggestion : How about making more curve point here ? It would fit with this vocal.
@Normal: Unstacked 02:01:805 (4,1) - cause it can make player miss read (and keep stacked at next patterns because 1/2 stacked slider is easy to catch for player :3).
