*Offset:+5ms~ (If you fix this don't forget to resnap all notes [go to Timing > Resnap All Notes]) Don't Know Armin
*I dunno if Mats/Bats will complain the star rating of your easier diff [Ranking guidelines say that this one should have a star rating below 3] I'll will talk with Hyguys and, when he apply the changes, he try to make the rating lower
*Add hyguys to tags, please. Okay

[Hyguys' Easy]

Your PreviewTime is different from all the difficulties. Please fix this manally.
Plus, this doesn't seem an easy. If I were you I'd call it normal. [due to doublets and more complex patterns]

00:25:130 (1,2,3,4,5,6,1,2,3,4,1,2,3,1,2,3,4,5) and 01:26:827 (1,2,3,4,5,1,2,3,4,1,2,3,4,1,2) - Aww, this clap flood doesn't seem really enjoyable during playing. I suggest you to add a 2/1 clap-pattern
00:49:809 (x) - I expected a hitcircle here because you were following the instrumental voice which is on 1/1(00:48:266 (2) <- just look at this slider's end)
01:36:467 (2,1,1) - I don't reccomend these hitobjects for an easier difficulty. Recovery time is really short and this will just confuse a new player (If I'm not wrong, Easy difficulties are for beginners, right?). I suggest you to remove the spinner and to map that part.
01:47:842 (5,6,1) - Uh, new combo on a stack, this may confuse a newbie. >_< Remove it here 01:48:228 (1) - and add this one here 01:47:842 (5) [in this case you'd follow also the vocal voice]
01:49:578 (x) As above, I expected a hitcircle here [Because previously you were following the vocal voice...] same stuff here 02:02:688 (x) [But in this case recovery time would be really short. In this case I suggest you to remove the spinner and the stacked hitcircles in order to make something easier, like: http://osu.ppy.sh/ss/99397 (see the timeline and...those replaced hitobjects if you like them ;P)]
02:39:320 (1,2,3,4,5) - a bit hard to read, eeeeh.

[Hard]

Increase Approach Rate and Overall Difficulty, they're quite low (your values are for a Normal difficulty XD) Okay

00:48:941 (1) - Make this 1/2 shorter, please; same suggestion here 01:50:637 (1) [It would make the next pattern more intuitive] Sure!
01:29:912 (1) - I'd add a new combo; idem here 02:31:608 (5) - Yes, and added hitsounds

I don't really like the huge copy/paste at the end D: Me too but I'm A stupid Lazy Boy XD

[Insane]

02:40:092 - 02:40:477 I expected some notes here XD Okay!
01:27:598 (3,4,5,6,7) - 01:29:912 (1,2,3) - and next copy/paste Would this be better if you followed the rhythm like you did at the start? I like this doubles, It's funny to play imo
For example 00:27:251 (3,4,5,6) [In other words: triplette + beat 1/2 BPM distant forward]
Nice Insane, I really liked your streams

Deserves a star.
