[General]
You probably don't need the 3rd red line, the offset is -4 to the 2nd one. but not your offset is just several ms early. Delete the 3rd one and change the 2nd one's offset to:10868 is probably correct timing.
I'll start from Insane, to point the hitsounds thing, it just needs a big change. i won't list again in the other diffs.

00:02:049 - 00:07:630 - Man, the clap, is an ECHO SOUND, what's the meaning of have an ECHO SOUND every second? you just hear it all the time like noise and that's not what hitsounds mean.
N=Normal, W=Whistle, F=Finish, C=clap
here's what i'll suggest:
NWN NNW NWN NNW NWN W NN NNCNWN
00:13:191 (1) - same thing start from here, the finish, do you know any bands use the heavy drum sound so frequently? remove every finish except for the first one, because it's where you start a pattern. And hey, i could see in every 4/1, the beat is N NC N NCN C N, could you use any other patterns plz?
00:26:214 (1) - Pattern repeat thing again start from 00:26:214 (1) to 00:37:377 (3), except for the stream, all i can see is N W C WNN W C WNN, yes, all the time, without change even once.
00:37:377 (3) - this sliderwhistle is fine. but in other places, there're many sounds just noisy. you should probably check this thing yourself.
00:40:866 (1,2) - huh? the vocal is on a "up" pitch but slowly, why you do need a huge jump like this?
00:52:959 (3) - remove finish. basic music theory.
00:54:935 (1) - better if you could end at 00:55:982 -, add a circle at 00:56:330, then change both of them to whistle.
01:01:563 (1) - start from here, remove those finishs plz.
01:05:749 - if you're trying to follow the drum, then follow it nice plz. you shouldn't miss this one. if you want to follow the vocal, you should change other parts. if you want both, you need to set another hitsounds for it.
01:40:633 (3) - here's a bad sliderwhistle, just for example.
01:44:121 (1,2) - huh?
01:56:214 (6,6) - the finishs are just misplaced.
02:03:424 (2,3,4,5) - not a good idea to use this pattern, because 3 is on a non-vocal beat and should be put in a light way.
02:09:005 - drum miss

Same main hitsounds issues with [Insane] (clap at the beginning, then the finishs)
00:20:633 (1,2,3) - ugly. move 3 right and down some. not stacked with 1's end
00:32:726 (6) - bad sliderwhistle
00:37:377 (2) - this is in fact ok but you should sliderwhistle on 00:38:307 (4) if you really want, it's in fact a symmetry part.
00:52:958 (2,2) - do you noticed those sounds weird...
01:14:121 (1,2,3) -who will know this is 1/2 until they start to hit yeah, people could recognize it by AR, but the spacing is really ugly, make it about the same just with common 1.0x spacing do no hurt to you.
01:56:214 (2,2) - hehe
02:01:098 (1,2,3,4,5) - any need to be that lazy?, hey,00:57:842 (1,2,3,4,5) - ?
[Normal]
hitsounds again. i won't list.
01:15:982 (2,3,4,5) - spacing plz? just guessing, you added 4 later, then forget to adjust spacing.
[Easy]
a quick check through, i guess no major issues.
few mistakes and few great points, that's what growing more and more in current osu maps, which i don't like to see.
