00:08:581 (2) - This stream seems lack movements. How about move 2 to x:64?
00:10:615 (2) - ^. Move 2 to x:384
00:12:310 (3,4,5,6) - ^. I think a zig-zag or V pattern could be better
00:14:014 (1) - You can actually make a move between 1 & 2, say move 1 to s:96
00:15:378 (1) - ^, so move 1 to x:512. However this is the edge of the screen, so possibly you need to move 1,2,3 to their left a little bit.
00:17:423 (1,2) - Replace these objects by a 1-beat slider.
00:24:582 (1,2,3,4) - Same as 00:12:310 (3,4,5,6).
00:27:990 (2) - Same as 00:10:615 (2).
00:43:671 (1,2,3) - There could be more movements here. For example,
[Salad]
Personal ThoughtsThis song is very simple and slow, so it's not a problem not to make too hard difficulties. However, I think you need to consider what levels of players would like to play your maps. The salad, as the highest difficulty of your map, should be the most interesting and challenging difficulty of your map, and at least able to draw attention from salad-level or even platter-level players. However, since it is only 1.23* difficulty, I doubt whether these players would really enjoy playing so easy a map (at least you'd better make a difficulty higher than 2*).
For your reference of spanning the difficulty levels, you may take a look at
https://osu.ppy.sh/b/1265708. This is also a similar music box simple song, but it has quite an interesting difficulty (Imagination). I guess even platter players can enjoy it.
00:02:818 (1,2,3,4) - You can make more movements in this stream, for example, move 2 to x:64, 3 to x:132 and 4 to x:237.
00:08:581 (2) - More movements are needed. How about x:300?
00:14:696 (3) - Move it to its right like x:256
00:16:059 (3) - Move it to its left. You can even make a dash between 2 and 3.
00:24:582 (1,2,3,4) - More movements
00:26:968 (1,2) - How about forcing a dash in between?
00:32:081 (2,3) - It might be better to make a dash like 00:30:718 (3,4) -
00:36:854 - I think the slider tail can be cancelled here.
00:40:944 (1,2,3,4) - More movements
00:42:990 (2) - Move to x:160
00:43:671 (1,2,3,4) - More movements
I see that you put almost all your fruits at the main melody, but actually you don't have to. You can even put some objects during the intervals like 00:06:886 - 00:07:903.
