IlluminationNote: I'm not going to bother checking what the previous modders pointed out, I'm only going to assess your map based on its current version.
It's an alright map, plays ok too, but it could play better. I do think it could use a good bunch of tweaking here and there, and some patterns seem a bit random.
Since you don't seem like you're into using grid snap too much, I would recommend using distance snap to even out some gaps in patterns at least. There are many triangle patterns that are inconsistent and could use some repositioning. Intentional or not, I think it would be nicer to play and would certainly look better.
There are also many repetitive sliders in this map that look like they've simply been copied and pasted and then turned 90°. You should add more curves, as well as reposition them and rotate them to make them more playable and fun and less boring. It would also really improve the flow.
1) 00:01:861 (3) - I would move this slider to the left so that it points more towards the center blanket of the first slider.
2) 00:02:172 (4) - You could make this a blanket for (2). If you necessarily want the same shape as (3), you could reshape (3) according to this.
3) 00:02:638 (2) - Perhaps you could move this so that it'll create (an evenly gapped) triangle pattern between 00:02:482 (1,2,3)
4) 00:02:794 (3) - I think you could curve this more downwards so it'll flow better to 00:03:105 (4)
5) 00:03:105 (4,5,6) - You could also make these form a better triangle by evening out the gaps.
6) 00:04:504 (4) - Same thing as 3)
7) 00:06:214 (1,2,3,4,5,6) - This pattern doesn't look that nice imo, so you could move (2) and move a triangle pattern with (1) and (2) so that (6) remains in the center of the triangle. You could then move (4) and (5) too to create another similar triangle pattern.
8) 00:07:457 (1) - Maybe rotate this a bit clockwise so that it flows better to (2).
9) 00:08:079 (3,4,5,6) - Similar thing as 7). I'd move this pattern to the left more so you'll have room to make a better triangle out of (4) (5) and (6) and place the (3) precisely in the center of it.
10) 00:10:799 (4,5) - I'd make these expand a little slower, and with that I mean, increase the spacing more gradually and not so suddenly, and with that I mean, not stack them that much.
11) 00:16:161 (1,2,3,4,5,6) - You could even out the gaps a bit more in these triangles. (For example, click on (2) or (5) and you'll see the Prev: and Next: on the top right have different values.)
12) 00:22:535 (1) - Maybe you could blanket the starting point of (3) with this (and then move the rest accordingly). And maybe stack the ending point of this with the start of 00:21:602 (2) ?
13) 00:29:374 (4,1) - Could blanket these a little better.
14) 00:39:322 (1) - This combo change feels quite unfitting. Either change the combo from 00:39:166 (4) or just remove the new combo.
15) 00:43:830 (2,3,4,5) - I think you could form another proper triangle here with (5) in the center.
16) 00:46:316 (2,3,4) - Could perfect this triangle too.
17) 00:51:912 (3) - Maybe curve this more so that it blankets 00:52:379 (1)
18) 00:54:089 (3) - Maybe twist the end here a bit so that it points to (4)
19) 00:56:732 (4,1) - The blanket here is just a tiny bit off on the top.
20) 01:06:369 (3,4) - I think this blanket could be improved just a little bit as well.
21) 01:09:943 (1) - Again, this combo change feels kinda unnecessary and unfitting.
22) 01:24:556 (1,2,3) - Would reposition the (2) here a bit so the distance from it to 1 and 3 is equal.
23) 01:25:487 (6,7) - This pattern is a little weird. I'd reposition the 6 and 7 so that they're perpendicular to 4 and 5. Would flow better too to 01:25:799 (1) (So move 6 a bit to the left and move 7 up so that it creates this sort of diamond shape)
24) 01:33:105 (1) - Would make this a blanket for (2). Also, you keep repeating this same slider shape way too many times during this kiai. Might wanna change them a bit for more variety so it doesn't get boring.
25) 01:37:768 (2) - Same as 22)
26) 01:38:701 (7,8) - I think you should do something else with these. Their current positioning doesn't flow well at all and is quite bland.
27) 01:41:809 (1) - I'd rotate this clockwise a bit. Or curve it. Feels a bit awkward as it's now.
28) 01:42:587 (3) - Would place this a little higher to make this star look a bit better.
29) 01:47:250 (2,3,4) - Could make these flow a little better by pointing (2) more towards the circles, or moving the circles themselves.
30) 01:49:425 (2) - Maybe move this closer to the (4) slider so you'll get this narrow X pattern going here. It could use a better pattern in any case.
31) 01:51:291 (1,2,1,2) - These new combos don't really fit here either. They just feel arbitrary, I can't really recognise any part of the song that would make these fit.
32) 02:02:482 (3,4,5) - Could even these gaps out. They're not precisely evenly far away from each other.
33) 02:13:363 (3) - This circle stacked under here is kinda awkward all on its own. You should just add it to the stream and not stack it, it's not very nice to play. I know you'll run out of space against the left border but you can just curve the second slider or move the whole combo to the right.
34) 02:19:736 (3) - Not so sure if this should be a reverse. The sound which would allow this is kind of minimal, especially compared to 02:20:513 (1) which is an identical reverse slider. It's mainly just boring repetition otherwise.
35) 02:27:974 (1) - Could curve this more to improve the flow to 2 and 3. I see you use this kind of generic slider very often in this map. I suggest you add more curves to them and not simply flip them by 90° which is kinda the impression I'm getting from this.
36) 02:31:550 (1) - Same thing.
37) 02:38:855 (1,2,3,4) - I'm sure you could come up with a more exciting pattern here.
38) 02:42:897 (1,2) - Would move these up so the angle from 02:42:741 (4) to this is the same as from 02:42:430 (2,3)
39) 02:45:228 (4,5,1) - Would position this stack so that it creates a perfect triangle with 02:45:073 (3) and 02:45:539 (2)
40) 02:48:337 (4,6) - Could blanket these.
41) 02:49:114 (1) - I'd really just stack this with the slider's starting point. When they're placed like this, they sort of give me a headache.
42) 02:49:892 (5,6,7) - I would just move these way further away from (3). More to the lower right.
43) 02:52:223 (4,5,6,7) - I really don't like the way these are positioned. They don't stack so it doesn't look that nice either, and they don't play well. Maybe just move (6) and (7) somewhere else?
44) 02:56:731 (2,3,4,5,6,7) - I think you should increase the spacing somewhat more here. Also the reverse slider + circle after it would look better if they were aligned in the direction of the stream.
45) 03:02:793 (1) - Could make this form a better triangle with (5) and (6).
46) 03:06:679 (2,3,4,5,6,7) - You should preferably make this stream go towards the opposite direction for better flow. Also maybe increase the spacing just a bit.
47) 03:07:767 (1) - This combo change feels kinda unnecessary considering how small it is.
48) 03:11:809 (4) - Again, this part is full of very similar either horizontal or vertical sliders, I really recommend curving them around and changing their directions to add variety. Anyway, to make this part flow better, you should flip this horizontally. Then make it point towards (5).
49) 03:13:674 (5,6) - This pattern could really be more exciting. Maybe move the 5 up for a more triangle shape.
50) 03:13:985 (1) - This slider's just completely against the flow. You should just rotate and curve it downwards. It's just so generic-looking along with the dozens of other sliders that look exactly the same.
51) 03:15:073 (6) - Would reposition this for a triangle shape between (5) and (1).
52) 03:16:161 (5,1) - Would blanket these. Move the (1) slider a bit lower so that it blankets (5) as well as curves towards (2) so that it doesn't break the flow.
53) 03:17:871 (2,3) - Make these flow better. Point the slider directly at the circle.
54) 03:33:259 (1,2) - I'd make these more interesting by curving them and then mirroring.
55) 03:43:208 (1,1,1) - These aren't perfectly blanketed.
56) 03:51:601 (3,4) - This blanket's just a little bit off.
57) 03:54:399 (1) - This is pretty unfitting. I'd just remove it but if you really wanna keep it, move it to 03:54:710 instead.
58) 03:56:576 (2,3,4,5,6) - Could perfect these triangles.
59) 04:06:835 (4) - Same thing with the sliders going on here again. Would really at least curve this to improve flow to 5.
60) 04:07:301 (1) - Would curve this too so it'll flow better to (2).
61) 04:11:187 (1) - You should make this stack with the rest of the stack.
62) 04:11:964 (4) - Same here.
63) 04:12:897 (4,5,6) - This is a really arbitrary jump. Nothing in the song gets more intense here. Just do something else with them, and especially with the slider which is (again) just pointing towards the border and flows horribly. Rotate it, reposition it, curve it. And move the circles.
64) 04:13:519 (1,1) - Just do something else with these. You should stop being lazy and form some unique looking sliders out of these that actually flow well.
65) 04:16:783 (1,2,3,4) - This is just a really random and ugly pattern, consider making something else out of it. Also 04:16:472 (4) doesn't flow well to it at all.
66) 04:29:373 (2,3,4) - You should improve this triangle as well.
67) 04:30:462 (1,2,1,2) - Again, I feel like these combo changes don't fit here at all. Nothing really justifies them, not the song either.
68) 04:31:705 (1) - Same here.
69) I really don't know what to think about ending. It's pretty long and awkward. The long slider doesn't really fit here, but neither would many spinners. And a single spinner would be too long. It might be that you'll have to end up removing the slider and maybe replacing it with a spinner that lasts until 04:49:736. This would, however, make it a non-marathon map because of the length, so you'd have to get other difficulties in as well. In any case, 05:02:171 (1) is completely unnecessary so you might as well remove it.
So yeah, your mapset needs a lot more variety (especially with those sliders) and better patterns. Most of them seemed completely random and the flow was often bad as well. It might be that this can't be approved as a marathon map because of the ending, but I guess you'll just have to see about that.
If my mod was of help, consider giving me some kudosu for it, I worked hard on it!
