[Easy]
00:00:833 (1) - Add Finish at the Start Point.
00:02:056 (2,3,4) - Flow is very disturbed, it looks like a Jump, even it is not one.
01:03:950 (1) - Please hold here 1/1 beat. Because nothing of the Music or the voice fits with the Slider.
01:14:056 (1) - ^
01:33:634 (2) - IMO the Whistle sounds weird and should be removed.
02:12:161 (1) - Same like 01:03:950 (1).
02:22:266 (1) - ^
02:39:634 (3) - Place it at x:192 y:60, looks better with the curve.
02:50:056 (1) - Remove Clap from the Middle Point, it does not fit there.
03:04:898 (2) - Form it to a 1/2 Slider. Fits better with the Voice. But it's up to you, because the current slider is also fine.
03:10:266 (1) - Same like 01:03:950 (1).
03:20:371 (1) - ^
[Normal]
00:01:465 (2,3) - The (3) is not readable, so move the (3) somewhere, but do not stack it.
00:48:477 (4) - This buckling could irritate beginners. So do something here.
00:50:371 (2,3) - This could be too fast.
01:13:424 (3,4,1) - Feels too fast to play. Please remove (4).
01:31:424 (4) - You should remove Whistle because it sounds off from the rhythm.
01:49:424 (3) - NC
01:49:740 (1) - Remove NC
01:53:213 - I suggest to add a Circle here to fill this empty part.
01:54:477 (1,2) - Remove the Reverse Arrow at (1), delete (2) and set from 01:55:108 to 01:55:740 a Slider, the singer hold her voice so you could also do this with a Slider. Anyway, it should look like this:
http://puu.sh/HFej03:36:792 (1) - NC isn't neccessary.
[Hard]
The whole seems like an easy Insane, obviously. The AR should be AR7 and not 8, the SV is IMO a bit high and they are parts like 00:44:056 (1,2,3,4,5,6,7) it let looks like Insane-related.
01:31:740 (1) - Remove Whistle from the Slider, but please hold the Whistle at the Start.
01:32:371 (3) - ^ but remove only from the Start Point the Whistle.
[Lunatic]
Looks fine.
I strongly suggest to make Hard easier. Because to make a new Diff for it would be not so good and you would need to get some more mods again for the diff.
