[General]
BG pls.
00:08:694 - I don't really like this.. it feels weird in all diffs.. especially in hard, I think People will have Problems with that, do you have an idea how to fix that elsewhise? You could at least add a NC where you have something clickable to make it hearable.
[Beginner]
00:10:004 (1,2,1,2) - I honestly don't like this pattern, it does not flow well, and it looks pretty odd. I get your idea of making a duplicate (because of the song), but it doesn't really work imo. Something like CTRL+H+J on the pattern would also show up the equality of the song, and it flows way better as well.
00:47:448 (2) - Remove NC, it feels spammed.Well you couldn't do much wrong here, but basically it's a 2/1 slider circle circle pattern which seems quite boring to me.
[Easy]
00:13:307 (3,4,1) - The way it overlaps here doesn't really look clean. You can see it ingame.
00:17:713 (3) - Move that one slightly up to improve the transition?
00:39:189 (2) - Well quite nazi but blanket.
00:43:043 (1) - Check the DS, it's quite noticable. Also, what do you think of a pattern like this?

01:19:937 (3,4) - Not exactly sure why you go for a such straight pattern here.. I have the opinion that things like this don't really play confortable in an easy, a zig zag or a curvy pattern is easier to get for beginner player, if you think differently it's fine tho.
[Normal]
I think the diff itself is fine, but I don't really agree on the spread between Normal and Easy, the Normal seems really hard to play, imo! You have quite many 1/2 Patterns, which is alright, but things like these 01:14:431 (3,4,5,6,7,1,2,3,4) - have a quite big difficulty spike, I would soften them slightly.
[Hard]
00:26:661 (2,3,4) - If you can read maps well, this is not a problem to play. But we are in a hard here, so.. I think it is too hard. Try to get a less intense rhythm here as well please.
00:35:334 (1,2,3,4,5) - Keep these hard Patterns for insane.
01:03:968 (1,2) - This is a hard diff. A hard diff and not insane!
01:05:070 (1,2) - ...
01:07:272 (1,2,3,4,1,2,3,4) - a hard diff, I mean even if it might seem easy to Play, it's all stacked and definitely too hard for this diff!
01:18:010 (3,1) - ..
I'm shocked that you say this is a hard diff.
[Insane]
00:16:611 (1,2,3,4) - This should be 1/2 imo, and not Extended sliders. I at least don't hear it in the Music (25%)
00:34:233 (1,2,3,4) - ^ it doesn't really Sound good either, if you insist leaving them (what I don't Support at all) you could at least try to silence the Ends.00:43:043 (1,2,3,4,5,6,7,8) - This has the same Sound and here you have 1/2? (it's fine, just showing you)
01:17:459 (7) - Blanket issues, I think the whole pattern could be redone a bit (because it doesn't look too clean)
[DARKNESS]
00:16:611 (1,2,3,4) - Same as in insane00:34:233 (1,2,3,4) - Same as in insane00:05:368 (2,3,4,5) - This plays extraordinarily bad.. it follows the song, but I'm not suggesting you to use such a crazy spacing with 1/8 etc. etc., you should get what I mean, I completely agree with Asphyxia here.
00:35:609 (2) - A slider would fit the song really well.
I'm not sure if this is too playable because of the 1/8 or even 1/16.
Sorry for the quite short mod, but I said the most important things, the maps themselves are pretty clean, so not much to say.
About the spread, I highly recommend you to rearrange the stuff, because Normal is quite hard (maybe rename to hard) and the hard is definitely Insane..
Good luck.
