Since it's pending I assume the mapset is finished and there won't be any more diffs.
My biggest concern about the mapset is the lack of actual spread and absence of some difficulties like Normal, Hard, Insane, Extra (between your "Insane" and top diff).
1st: There is almost no difficulty progression as in the rhythm as in the way how they are mapped. Let's take Hard for example. In Hard you use many consecutive chains of active/passive 1/2 rhythms overall are allowed in hards, but in this case the song's bpm is 215 which decently complicates the diff and turns it into light insane. Furthermore, you make the diff harder by using high default sv (1.50x is high for 215 bpm) and weird inconsistent stacks like I mentioned before in #1326547 , #1326560 .
2nd: The absence of some diffs is caused by the reasons I pointed out in the 1st. For example: there are no diffs to fill the gaps between 1/1 and 2/1 rhythms on Easy and some 1/2 sliders and circles on Normal, many 1/2 rhythms and some 1/4 on Hard and 1/4 bursts and actual jumps on Insane etc. you got it. The problem is the diffs are unreasonably different from each other and one is a lot harder than the previous diff.
The best solution is to map or ask someone to map actual Normal (the current one is more like Advanced), Hard (which is more like Light Insane), Insane and Extra between your current Insane and top diff, or just to simplify the mapset so the rhythm will be appropriate.
I'll add on to this by restating the most important point:
This mapset needs a 6* difficulty; 5.39-7.19 is too high of a difference to be rankable.
the rhythm choice and progression has been updated to show clear progression between the difficulties. now highest sr is 6.99* and the each difficulties show different rhythm choices that are appropriate and spread is well rounded now. There maybe a GD coming in at 5.9 ~ 6.2*
