Inconsistence Widescreen Support, you should fix it.
Remove Letterbox? If it's intension, it's no problem.
Delete "mystery" in Tags, it's contained from music name so it doesn't need.

AR4 would be fine because this song is low BPM and it's a easiest diff, so for newbie it looks difficult.
PlacementUse distant snap on every note, it's a Normal diff and there is no Easy diff, so for newbie changing distance from note to note is really confused.
WikiIf you don't have an Easy, you want to make it so that newbies can still play your map easily.
00:49:445(1,2) This 1/2 stack doesn't recommend for the easiest diff, it's suddenly appeared so newbie would be confused.
Ok, stopped.
I hope you remake this diff, and if you do that I'll again check on this diff.

Placement00:15:945(3) Add NC here to be same Insane.
00:57:695(59 Move like this and make a blanket? there are a lot of similar placements so it looks suitable.
01:03:445(1,2,3,4,1) It looks a bit odd flow for me, set same height or move consistent upliner movement better. e.g.)
03:30:445(2) Move thi note a bit right like this, and the placement looks like nice triangle.
03:43:445(3) You placed a note away on the previous same part at 01:19:445, but in this part it's so nearly from previous note. I know it's a last note, but try to put this note away better.
Rhythm01:36:945(3) Sounds weird because you don't pick the vocal at 01:37:195, I don't suppose it ie better to ignore this point.

Placement00:08:445(2) Liner slider better than curved one to be symmetrical placement with (1).
01:10:445(2) CTRL+G would be better to make a same pattern.
01:16:945(3) Just move this slider on the left at 3 grids, current spacing is a bit narrow and seems not good.
01:19:445(5) Why this spacing is ×0.8? It looks a bit confused so just set ×1.0 better.
03:43:969(4,5) ^
01:36:945(3) The end tick of slider is off-screen, I suppose you can place this slider in the grid.
01:39:195(6) Bent this slider's direction for next note, and the flow would be nice.
Rhythm03:00:945(2,3,4) I suppose 1/1 reverse slider would be better than current one, the vocal has keeping on this part but not emphasized,
Hit SoundWell designed mapset except Normal, I can't find big problem.
Good luck.
