Well, I have to say good job so far, there really isn't much for me to really crack down on (granted I'm only looking at hard/insane here).
So this is gonna be me nitpicking, although I'm pretty sure that's what you want anyways.
HARDFirst off, Might just be me, but I feel the AR is a little oddly slow for the map and makes it look faster than it actually is, I'd recommend a slight increase to 7.5 or 7.7
00:18:000 - (1,2,3,4) - This Pattern here feels very robotic to play, Id recommend increasing the spacing so that the tails of each are about at the same level and angling the sliders towards the next combo.
00:31:950 - (1,2) - This flick feels a little strenuous for a Hard difficulty, I'd reduce the spacing here slightly.
01:58:350 - (3,4) - I'd recommend slightly spacing these two, the lack on consistency from the flick last time this pattern occurred is visible
02:17:700 - (3) - I don't like the angle of this slider, I'd recommend tilting it slightly so that the head is closer to the tail of the previous slider and that the tail leads to the next slider properly.
03:27:000 - (3,4) - Listening to the song I feel like these two sliders should actually be one longer slider, if you want to cut the length you can always make it snake on 1/12 or 1/16 snap to reduce speed and length.
04:25:650 - (2) - This circle is very high on the grid, while it doesn't seem to have any errors while playing I wouldn't want to take chances with a note that's half off the "map able" grid.
That's it for the Hard, if anything else I'd say it feels very difficult for what's supposed to be a "Hard" map, but seeing as the difficulty spread holds alright it shouldn't be a problem.
INSANE03:15:300 - 03:37:200 - Honestly, This whole section, There should be notes starting from the initial time there, and when you did have notes later, I felt like they weren't highlighting the guitar which was the dominant track and would've been very fun to play, I'd recommend remapping this entier segment with that in mind.
Yea honestly, Outside that one segment, I didn't see anything I'd want to change in the insane, I played it through maybe 5 or 6 times modding it alone, I could see my self playing this enough to learn and SS it. the Insane is a very good map and I hope you get this ranked soon, GL.
