Let me remind you: this is the first time I've ever modded a map formally. I might be very picky, but that's because I don't have that kind of experience yet.
Try changing the offset to 14,560.
Normal:
00:18:73 (3) - You might want to cut this slider by a beat.
00:20:14 (1,2,3) - There is always the risk in Normal maps that most targetted players will not get this kind of spacing. It's a bit more of personal preference, but shortening the gap would be nice.
00:26:49 (2) - Too far.
00:29:32 (2) - Ditto.
01:10:26 (1,2,3,4) - A bit tricky for a Normal map, whatcha say?
01:37:44 (4,5) - Ditto.
01:47:32 (2,3) - Ditto.
01:48:73 (2,3) - Wild Ditto appears!
02:09:55 (1) - Same problem with 00:26:49 (2).
02:10:97 (1) - Ditto.
02:12:38 (4) - You might want to place this a bit further.
02:28:26 (2,3) - Same problem with 01:10:26 (1,2,3,4).
02:30:91 (5) - More of a personal preference, but I think the start marker should be 1/4 late.
Hard:
02:27:91 (1) - Too close.
Insane:
I don't know if an HP drain rate of 10 is really fair. The HP drain really drains, and I mean that negatively. Maybe an 8 will suffice (it's still pretty hard on an HP drain of 8, mind you).
00:55:26 (6,7,8,9,10,11) - You might want to rearrange the placements of these beats, though I can let it pass since it's an Insane map.
01:20:67 (5, 6) - Ditto.
01:53:32 (4) - It's too close. Place it way further.
02:07:61 (9) - I don't know if placing the start of the slider diagonally away would work. You might want to change that.
02:24:91 (3) - Same problem with 01:53:32 (4).
02:30:91 (8) - Doesn't sound right. Maybe changing the long slider into a short repeating one will work.
Don't be discouraged by what I've pointed out. Your map looks great already.
