All suggestions based on playing your map ~
Easy:
- There's a lot of 1/1 single notes in this diff that are kind of boring like 00:34:525 (1,2,3,4,5,6) - and 01:20:239 (1,2,3,4,5,6) - I'm sure you can do something more creative with these ^_^
00:29:382 (2) - I'm pretty sure this will be really confusing for a new player. The ticks don't show where the slider goes and it overlaps on itself. I'd recommend using a different shape.
02:44:811 (1) - This slider shape is will probably be confusing for new players, especially at this SV. Use a different shape?
Yli's Normal:
00:41:382 (1) - Remove normal whistle from the end?
00:42:525 (3) - ^
00:45:954 (1) - Whistle the whole slider except the end, like 00:50:525 (1) -
00:47:097 (2) - Remove whistle, it sounds odd imo.
00:51:668 (2) - ^
01:49:954 (1) - Remove new combo.
02:11:097 (3,4,1,2) - Overlap is kind of confusing imo, I think it'd play better spaced out more. Also the combo pattern here is strange compared to the rest of this section.
02:21:954 (1) - Remove new combo.
Hard:
00:20:811 (5) - Finish?
00:21:382 (1,2,3,4,5,6,7) - Too much whistle. Remove whistle from the red ticks?
00:55:097 (1,2,3,4,5,1,2,3,4,5,6,1,2,3,4,5,6,7) - I don't understand why the spacing slows down here. This part could do with some jumps or patterns similar to the previous section to make it more fun.
01:06:525 (1) - to 01:17:668 (4) - Have you considered using custom hitsounds here so you can combine normal hit and soft whistle? Right now the change between normal and soft hitsounds seems strange because you can clearly hear the drum in the background.
01:17:954 (1) - Move this down about 5 squares (grid 4). It feels too close to 01:17:668 (4) - right now.
01:45:382 (5,6,7) - Why not use the same rhythm as 01:38:525 (1,2,3,4,5,6,7) - here? It will make a better ending for this section imo.
02:02:811 - Note?
02:03:382 - ^
02:44:811 (1) - Ticks sound too loud! Around 50-60% volume sounds good imo.
Good luck!
