GeneralYou need to set a preview time. find a point that represents the song and Timing > set Preview Point. do this in the exact same position in all difficulties. Second red line sounds off. Offset seems anywhere in the range 52392 to 52402. Try 392.
Easy00:11:762 (1,2) - For consistency these should have claps on the ends.
00:38:859 (1,2) - IMO if you're going to shift a pattern, it needs to be a meaningful shift. It needs to great enough to make a difference. The change here is not great enough to escape the "It looks like an error" feeling. I suggest lining up the shapes or designing so that each transition is more meaningful.
00:42:730 (3,4) - ^
00:44:666 (4,1) - I don't like this overlap. I suggest changing it so the slider ends exactly in the middle of the other slider.

Normal00:04:020 (1,2,3) - I see no reason why this spacing should be different.

Okay this is a recurring theme.
00:15:633 (5) - New combo.
00:15:633 (5,6,7) - Spacing
00:23:375 (1,2,1) - ^
00:25:311 (1) - New combo for consistency
00:26:762 (2) - This should be following the curve of the slider. Either adjust the slider to point to the note or move the note.
00:31:117 (1,2,3) - spacing.
00:38:859 (1,2,3) - ^
00:40:311 (2) - Should have a hitsound
00:40:795 (3,4,1) - Spacing is slightly off
00:42:246 (4) - Clap finish sounds bad- remove clap?
00:42:730 (1,2,3) - Have a more defined curve here
00:44:666 (3,4) - spacing should be the same as 1,2,3
00:46:601 (5) - New combo
Ending is missing hitsounds
Hard00:04:020 (1) - Sounds quiet without a hitsound on it.
00:04:020 (1,2) - This is just too close.
00:05:956 (3) - Kind of random to switch to a straight slider all of a sudden. Also quiet without hitsounds.
00:05:956 (3,4) - too close.
00:07:891 (1,2,3) - Quiet (the gaps on both sides of 2 are varying lengths) all the stop and go through this slider just plays badly. It's not hard, it's just weird.
00:17:569 (4,5) - Quiet
00:19:262 - You should have a note here.
00:19:504 (1,2) - Quiet
00:23:375 (1,2) - ^
00:31:117 (1,2,3) - Don't space things so closely at this approach rate. It's awkward.
00:34:988 (1) - Why is there a random finish on this? This doesn't follow any hitsound pattern you are using. (whistle sounds better on the end)
00:34:988 (1,2,3) -
Bad spacing00:36:924 (3,4,1) - Spacing could be exactly 0.6
00:38:375 (4) - add whistle?
00:40:311 (3) - ^
00:42:246 (6) - ^
00:44:182 (3) - ^
00:46:601 (1,2) - Quiet.
00:48:537 (3) - New combo to be consistent.
00:50:472 (1,2,3,4) - Quiet
Ending is too loud.
InsaneThis is 100% old school.
00:04:020 (1,2,3,4,5,6,7,8) - Such a dull pattern. Also there is no reason the spacing should be changing. Make the spacing consistent.
00:11:037 (2) - Whistle on end?
00:11:037 (2,1) - I would prefer the spacing here to be larger, but I guess it doesn't have to be.
00:13:940 (2,4) - Whistles on start?
00:14:666 (5) - Repeat cannot be hidden. this is unrankable. also ending the slider with a whistle sounds good.
00:15:875 (3,4) - I would prefer 1.2 distance spacing here. (The stream is 1.2)
00:21:198 (5,1,2) - Old school way of increasing the difficulty. Most do not prefer old school. But technically its a valid way to map this.
00:19:504 (1) - Sounds spammy with just claps. how about clap, clap, whistle, whistle or include whistles somewhere in it.
00:32:085 (6,7,8) - Quiet.
00:32:085 (6,7,8) - Add clap on end.
00:41:400 (6,7) - It would play better if one of this sliders was higher than the other one.
00:48:537 (1,2,3) - Quiet.
00:51:198 (5) - Whistle?
00:23:375 (1) - the first pattern had hitsounds here. this should as well.
