[General]
BPM 150.000, offset 6,619 sounds better imo.

Why "style"? Why not just "Easy", etc...?
Your preview point isn't actually part of Easy/Normal...
Combos felt weird in all diffs.
[Easy Style]
00:38:644 (1) - The song really only starts here; remove the spinners before it, they're not particularly fun to play. In fact, you could start it as late as 00:51:443 (1).
01:09:861 - Lack of a note here is weird.
01:17:839 - Add a break?
01:17:439 - Unused timing section.
01:21:339 - Unused timing section.
01:36:637 (1) - Combos are awfully long in this section.
I dunno, even for an Easy, this feels quite boring. Maybe it's just that I don't like the song too much.
[Normal Style]
OD feels too low.
00:29:046 (2) - This looks terrible.
00:51:443 (1) - Consider just starting here.
01:10:440 (7,1,2) - Very hard to read.
01:21:839 (1,2,3,4) - Unreadable.
01:23:638 (1) - I didn't really like the use of notes and repeats in this section; it feels like they were placed randomly to follow a constant 1/2 pattern rather than follow some aspect of the music. It feels repetitive, just how long it is, too.
01:50:835 - Unused timing section.
[Hard Style]
Those fast sliders felt weird, especially ones that start on red ticks and end on white.
00:51:443 (1) - Once again, just start it here. The kicksliders at the beginning don't really fit, and the high OD + no bass after it is quite hard to play. It would also cut your score to below 10m, which is always good.
01:21:839 (1,1,2,3,4,1) - Err, this placement is weird.
01:26:238 (10,11,12) - Blah.
01:42:236 (10,11,12,13,14) - I know some people don't like zig-zag sliders.
02:00:234 (1,2,3,4,5) - Not readable at all.
03:00:226 (1,2,3,4,5,6) - Weird pattern again.
03:07:025 (14,15,16,17,18) - Really don't like this formation, and don't like combos going so high. The twisty formations after this one aren't cool either.
Good luck!
