[General]
You should change your E/N/H naming to N/H/I. I really think the difficulty level of each map warrants it.
Having a combination of CS5, AR8, SV 2.40, and 1.2x BPM on a Hard is just silly, even with a BPM of 70. They're fine settings for Insane, though.
[Easy]
01:05:121 (3,4) - There are a lot of places in the map with this rhythm of (1/2 slider, white tick note) that misses the beat on the blue tick. Is it possible to extend the slider to 01:05:764? You could apply that rhythm to other places too if you wanted.
01:44:093 (2) - For some reason I hit this at 01:43:665 and broke my combo. I can see the distance spacing is correct, but it still feels weird. What do you think?
01:53:951 (3) - Increase distance spacing to 1.1x for this note to get rid of the slight overlap.
01:54:808 (1,2) - Same with these, and move (1).
02:01:665 (1,2) - Same with this, and make sure (3) is properly stacked on the end of the slider. At the moment it's off by one unit (75,283 instead of 75,282).
02:11:093 (4,1) - Maybe shift (1) down a bit to increase the gap?
02:29:951 (2) - You could blanket this a bit better.

[Normal]
00:21:407 (5,1) - Increased spacing looks more like a placement error than intentional.
01:00:835 (3,4,5) - (Minor) Spacing slightly off here.
01:45:379 (2) - There's nothing here in the music, so personally I'd delete it. Also 01:47:093 (4), 01:48:808 (2), 01:50:522 (4).
02:14:736 (7) - Why is the spacing on either side of this at 0.9x? I'd drop this slider down slightly or move (6,1) to keep it at 1.0x like the other slider runs in this section.
02:40:236 (2,3,4) - Want to continue this triple stack at 02:43:665?
02:51:379 (3,4,5) - If you do the previous suggestion, maybe change this stack to a slider.

How is this light? o_O
00:27:407 (1,2) - Is this intentionally unstacked?
01:01:692 (1,3) - ^
01:02:121 (2,4) - ^
01:37:879 (2) - Maybe new combo so that all the groups of 3 are their own combos?
02:05:522 (2,3) - You could blanket this.
02:18:808 (1,2,3,4) - For consistency, I think these would play smoother as a triangle like 02:09:165 (2,3,4) and 02:24:165 (5,6,7) and 02:39:379 (1,2,3,4) and 02:53:093 (1,2,3,4).
[Hard]
00:27:407 (1,2) - I don't see any reason why these shouldn't be stacked like the other difficulties.
02:11:522 (6,1) - Maybe move (1) farther from (6) so that it's more like 01:02:978 (6,1) and 01:16:692 (7,1) and 02:18:379 (3,1) and 02:25:236 (6,1).
Change the difficulty naming, maybe do some minor tweaks, and this mapset is perfect for ranking.
