first at all: you did a really nice job for guy who have only 7 maps
There is only two really bothering thigs in this map
First one: Hitsounds
They goes not so good with the song, and that hitnormal really annoying.
Some years ago i collabed this song with irreversible, so there is the link to refference
https://osu.ppy.sh/s/361740 (thought if you'll like hitsounding feel free to copy it with all these new progs people made)
The second one is these two gigantic breaks which ruin all the good feelings about this map. You really should consider mapping the first one (01:01:488 (1) - starting from here). Second one is okay until strong beats arrives 01:27:821 (1) - here. There is nothing what you can't map here i believe!
Okay the mod itself:
Metadata probably wrong (i didn't checked by myself but i think that mapset i linked a bit earlier has right one, because in it's case it was checked many times, but oh well you better to recheck it)
[Insane]
00:44:988 (2,3,4) - personally i think it's not really good patter choise in this case, because after that curved repeat slider something more circlar flowed would be more more natural to go with.
See this00:47:488 (3,4,5,6) - what about making them more spaced between each other? It'll be nice for emphasising these sounds which appears here. Idea is right, just make it more jumpish
01:20:821 (2,3,4,5,6,7,8,9) - well, i see with what it goes, but it doesn't really feels nice here because this part is pretty damn slow. I mean, the whole part goes in that lazy manner and suddenly BOOM STREAM U WOT MAET xdxdxdx. I'd go with slider what would emphazise glitch sound here, or at least replace these circles by repeat 1/4 slider if you want keep 1/4s emphasised.
01:38:154 (1,2,3,4,5,6,7,8) - it's pretty much the same, but in this case it's suddenly appears after a long break, but if you will decide to map break feel free to ignore this point
01:40:821 (2,3,4,5) - something more jumpish please
01:46:154 (3,4,5,6) - same (already pointed why i suggest it earlier)
01:52:154 (1,2) - sudden 1/1 never was fine tbh,
this kind of rhythm would be way better01:55:488 (5) - doesn't really good as well, but in this case it's more about downbeat being unclickable, when being pretty much strong, consider something like
this[Hard]
Dunno if you just forgot about putting second kiai, but you should because of rules
01:22:154 (3,4,5) - idk, it's pretty strange to see 1/4 here when insane didn't had any at this point, you better swap it and apply 1/4s at the insane, when hard should get some 1/2
[Normal]
Just a daily remind: Second kiai please
Okay so, just change hitsounds, map these freaking breaks and this will be ready for ranking, good luck!
