Some personal suggestions for ranked
bg improvement
The current bg was slightly applied and modified to be more suitable for osu.

Too structurally simplistic in using 1/8 sound like https://osu.ppy.sh/ss/16710882/4476.
If you divide the song intuitively, the current expression is not wrong, but due to the nature of 4key, if you try to use all the sounds to the maximum according to it, there will be a visual gap with the excessive dif spike in a speedcore like this song. ya I think that a pattern that is extremely dependent only on jumptrill is created, and it is not expected to be more creative and other Changes will only feel monotonous.
If I could suggest as an example
https://osu.ppy.sh/ss/16710888/637f I think it is important to break away from the unilateral jumptrill structure by inducing a change of direction in this way or intentionally undermapping.
The current top diff is too concentrated in one direction, and I think that is the cause of the quality deterioration.
Overall, I think it is necessary to adjust the jumptrill and 1/8 use appropriately.
Hope this helps you in ranking this map.
Such a great set, coming from a Wacca player myself. Very well made! Just have a couple of points where offset could be a bit better for a few notes, but great job!
The bitrate of the audio is pretty low (128kbps), so you might wanna get a better one.
Here https://drive.google.com/file/d/1SUnZPiGcwV73lZFAW5HePnjxX3zCrovF/view?usp=sharing this one has a better quality (192kbps)
You shouldn't need to change the offset, I tried to make it the same as your curretn audio, but you could check it just in case.

don't think "last labyrinth" is an essential tag because the website only makes mention of Laur's first album
