[General]
The hitsounds need a lot of work...

[SB]
You should try adding in combobursts, since you have section-pass and everything.
0'20''864 - I think you should start the fade-in of the 'white' element at 0'21''002, together with the drums.
1'31''583 - Same case here, try start the fade-in at 1'31''820.
2'19''349 - For the '2' element, you should fade out completely here.

[Easy]
The SV's a bit fast, IMO. I'm just saying though.

0'05''864 - Start new combo here, coz long combo is not really recommended for Easy diffs, if I remember correctly.
0'13''364 - Start new combo here.
0'36''694 - I suggest that you combine [3] to [5] here to make a reverse slider like at 0'38''540.
0'42''232 - Add a whistle here.
0'46''848 - Start new combo here.
0'54''463 - I don't think a clap fits a spinner, maybe try a finish?
2'11''042 - New combo here.
2'12''426 - Spacing issue (too far). Please fix this. And don't forget to move the next notes to maintain the spacing.
2'43''580 - Add a clap at the beginning.
2'45''426 - Add whistles to the reverse and at the end of the slider.
2'53''059 - Add a whistle here.
3'07''348 - It's better to establish the same rhythm pattern here, so add a clap at the reverse, and...
3'09''656 - Add a clap here as well.
3'32''271 - Spacing issue, as in too far from previous note. Also, start new combo here.
3'39''656 - Start new combo here.
3'43''348 - Start new combo here, and...
3'44''271 - ... delete the new combo here.

[Normal]
There's too many claps here to my liking, especially during the chorus. Try to vary the hitsounds in here a bit. I'll give some suggestions, but the rest is up to you.

0'31''617 - Maybe add a finish at the end?
0'39''463 - Start new combo here.
0'44'771 - This slider really sound odd here, try moving it so that it starts at 0'45''002 instead.
0'54''925 - Delete [10] and [11], and then...
0'54''694 - ... Either put a slider or a spinner starting from here and ending at 0'56''078.
1'19''814 - Add a finish here.
1'42''896 - Add a finish at the end of this spinner.
2'16''119 - Add a clap here.
2'30''426 - Add a finish at the end.
2'45''195 - Start new combo here.
2'51''905 - ^
3'04''810 - ^
3'32''271 - ^
3'47''964 - Add a whistle at the end.

[Hard]
Same problem with hitsounds as in Normal, but you need to try changing the hitsounds yourself.

0'52''386 - Start new combo here.
0'56''771 - Spacing issues, and I don't think a mini-jump here is suitable, so move this closer to [4].
1'48''435 - Start new combo here.
2'06''896 - ^
2'07''935 - I don't know if this is a good idea, but you could try adding two more notes here and at 2'08''050 to really follow the guitar.
3'02''271 - Spacing issues here.
3'05''617 - Remove the clap here, please...

[Insane]
Erm, why do I feel Insane is easier that Hard?

0'52''386 - Start new combo here.
1'05''763 - Start new combo here.
1'59''743 - Maybe new combo here?
2'03''435 - Start new combo here, and...
2'04''358 - ... delete new combo here.
2'10''349 - Please, remove all the claps in this slider DX
2'15''196 - Add a clap at the end.
3'05''964 - Add claps at [6] and [8] here.

[Jump]
I don't know, but I think there's way too many antijumps as compared to jumps here. And some of the antijumps here really feel a bit too
sudden, though I can't be sure of this coz I can't play Hard maps.

1'19''365 - Start new combo here. Also, the stream is not really even, maybe you could try this? -->


1'39''204 - Add a note here.
2'43''003 - Maybe move this to 2'43''118? Or just delete sliders [2] and [3] and put this in instead -->


2'46''349 - Try removing this slider and just put a single note here.
2'50''290 - Move this so that it starts at 2'50''174.
