General- You should get some hitsounds in your map. Without hitsounds it's unrankable. And if you do, sliders like 00:12:338 (7) can be finished with a single note at the end and a clap on that note.
Katastrophe00:04:491 (2,3) - Try to make the flow on these two notes a bit better. Like move (3) downwards so the end of (2) flows into it. Maybe move it a bit closer as well.
00:08:414 (6,7) - Again, (7) off of (6) doesn't flow too well. Make the beginning of (7) a bit lower. Or move (6) up.
00:10:491 (7) - Move down a bit, the flow looks a tad bit off from (6)
00:11:414 (1,2,3,4,5) - (if you decide to move (7) down like I said) Move these down a bit as well.
00:14:184 (4) - I don't suggest having a slider this fast out of nowhere. You should have warning somehow at least. But if you don't I suggest keeping it at the same speed as the other notes.
00:34:030 (4) - Personally not a fan of sliders like that. If I were you I'd make it a bit more open.
01:10:491 (1,2,3,4,5) - I think these notes should be farther away from (11).
01:12:338 (1,2,3,4,5) - ^ same with these
01:28:953 (1,2,3,4,5,6,7,8) - All these straight sliders seem quite boring. I suggest curving some of them and making interesting patterns. Like different ways of getting to the next.
01:32:645 (1) - This is more of an opinion. I dislike that really large slider XDD. Maybe lower the SV a tad with this but not enough for it to be difficult to catch.
01:36:338 (1,2,3,4,5,6,7,8) - Same with these straight sliders
01:40:030 (1) - And again don't like the note here haha
01:43:722 (1,2,3,4,5,6,7,8,1) - You get the basic idea with these notes.
01:51:107 (1,2,3,4) - I'm just going to mark them so you know
02:15:107 (1) - This note is way too close to (6).
02:44:645 (6,7,8,9) - This seems like a strange overlap. But I'm unsure what I would do about this...
03:27:107 (1,2,3,4,5,6,7,8,1) - 03:34:491 (1,2,3,4,5,6,7,8,1) - 03:41:876 (1,2,3,4,5,6,7,8,1) - 03:49:261 (1,2,3,4) - I decided to mark the spots with the straight sliders which tended to seem a bit bland to look at. Consider making them more interesting.
Hard- Particularly I don't think smaller notes for an easier difficulty makes much sense. Consider keeping them the same size as [Katastrophe].
00:32:645 (6,1) - The flow from (6) to (1) looks a bit distorted from the slider end of (6) to the start of (7).
01:25:261 (1) - I see what you were trying to do with this slider but it didn't seem too appealing to look at. Just a personal opinion ^^
01:50:646 (5,6,1) - (1) look a bit farther from (5) than (5) is to (6). Consider moving (1) a tad bit closer to keep the consistent spacing.
01:54:800 (1,1) - Another opinion I typically hate double spinners, so this is more of an opinion but I'd rather not see that XD. Ofc it's not unrankable or anything.
02:13:261 (1,2) - The spacing here compared to 02:22:492 (1) looks way bigger. I'd suggest trying to keep the same consistency throughout.
02:31:723 (1,2) - Move (2) away from (1) since right now the spacing is too small.
Normal- Just keep in mind I'm unsure whether blue ticks are allowed in Normal maps. I'm assuming they would be to an extent but just keep that in mind. And if you do map an easy at a point only put those notes on white ticks (unless you have small reverse sliders)
00:15:108 (1,2) - The transition from (1) to (2) look off. Move (2) upwards, or at least change the front of it to face (1) a bit more.
00:59:415 (1,2,3,4) - Try to keep most of your sliders (especially in normal) curved. Long straight sliders are typically annoying and boring to play.
01:14:184 (1) - Move (1) a tad bit lower so it looks a bit better with (2). It's hard to see but it's like a pixel or 2 above (2).
01:22:492 (2,3) - Definitely move (3) over to the left so it flows with (2) better.
02:21:569 (1,2) - Move (2) a little to the left so it flows with (1) better.
02:59:415 (3) - Move (3) one unit up
03:01:261 (1) - You should make this face diagonally so it faces a direction in which (4) was going to take you. Like
