If you ask for help with a WIP set, you should always tell very specifically what you want people to look at and what you need help with.
Like right now what I see without any further comment of yours is that the Light Insane and Insane have an identical start, almost all sliders on the Light Insane are unsnapped which are absolute red flags that give the impression that you weren't even trying to make the set proper.
For your Insane your rhythm decisions are questionable to say the least. You don't focus enough on the actual details and drums in the background that allow for more dense mapping but instead use a very straightforward melody-based approach which often does not play fluently in higher difficulties, especially given the relatively low speed here. For example, why do you map a circle at 00:09:729 - when the sound there is barely audible even with lowered playback rate but completely ignore the prominent drumkick at 00:09:948 - and the more audible drum sounds at 00:10:824 - 00:10:934 - etc.
The part from 00:18:160 - to 00:24:729 - specifically looks like it belongs into a Hard or even Normal difficultywise, given the rich sound the song produces here, giving plenty opportunities to map more difficult rhythms more appropriate for an Insane difficulty.
Add to this questional aesthetic choices (or rather mistakes?) like 00:52:758 (4,5,6,7,8) - (seemingly random spacing changes in the quint) and 00:59:765 (1,2,3,4) - (messed up stack).
Overall my verdict on that Insane difficulty would be that it is flawed in design and should be remapped with a more specific idea on what that difficulty is supposed to do.
If you want this to get ranked, you should check at first what difficulties you need so you can figure out which difficulty should operate at which level of rhythm complexity in order to get a balanced spread in the end. Personally I'd recommend you to map from bottom up as I find it easier to reference the next lower difficulty to figure out whether a pattern is appropriate for my new diff or not.
