Alright i was asked to mod your map, but first things first,
You need a new mp3 because the quality of yours is blow 128 kbps which is the minimum quality required for ranking
I've uploaded a new mp3 i found that was high quality enough.
There are 2 different ways you can install the new mp3 on your map, the first is to just rename it so it has the exact same name as your old one and paste it and overwrite the previous one, the second one is to delete the other one and paste this one in the song folder then change the audio filename on each osu! file:

All timing points with the new mp3 should have -354 ms, the easiest way to do this is to select all timing points and do -354 to them like this:

You should probably reset your preview point on all maps as well.
Now on to the maps themselves.
[General]Would be nice if in your OP you said which diff is which, instead of using names totally different than the ones in the actual maps, going by SR i assume they are in order tho, so i'll mod based on that.
One of the things i love about this map is that it uses tick rate 2, good choice <3

You dont need Elly-chan in tags, since you're already the beatmap creator.
[Taikers Oni]00:12:072 (43) - Unsnapped!
00:12:497 (44) - Unsnapped!
00:12:989 (46) - Unsnapped!
00:13:095 (47) - Unsnapped!
00:13:308 (48) - Unsnapped!
00:13:521 (49) - Unsnapped!
00:13:734 (50) - Unsnapped!
01:10:861 (41) - Unsnapped slider end.
[Eternal Wandering]White combo color tends to blend with the background, plus thanks to it i missed this slider >border< 00:56:984 (5)
00:53:106 (1,2) - I seriously recommend you change these slider shapes, since you're using symmetry spacing shouldnt be a problem try
this?Also dont apply normal hitsounds meant for hitcircles to sliderticks.
[Secluded Child]Pretty awkward that this diff has a higher slider velocity than the Insane.
Try to not combine double stacks with singles in middle of a single stream.
00:49:841 (5) - Unintuitive slider i'd recommend you drop a repeat or change it somehow.
01:01:882 (4) - Slider doesnt fit the music.
You're pretty much mapping in a box mapping pattern, and i dont blame you because you're a new mapper and that's what new mappers tend to do, i would prefer if you would at least try to make some cool patterns that would make the map more fun to play.[Pereira's Hard]I'd say change the whole color set... all shades of purple are too similar with each other, and pure white hurts the eyes during kiai time.
01:06:167 (1,2) - These repeats are really unintuitive.
01:09:025 (7,8) - ^
I like what you did at 01:25:759 (1,2,3,4,5,6,7,8,1,2) more than the previous 2 ones.
[LRJ's Normal]Probably the best map in the mapset, just wanted to let you know, no errors found.
[Easy]And here my heart breaks </3 tick rate 2 please D:
Nevertheless good mapset, deserves an SP star, however it still needs some more work before star icon.
After all changes are done since you're removing images from your song folder and adding a different mp3 dont forget to FULL SUBMIT
