Insane:
First off, let me say that this difficulty, plain and simple, is a very fun. With that being said, I can't just let these mistakes go unsaid. The main mistake in this difficulty is definitely flow.
00:22:403 (8) - Reverse selection (ctrl + r). Your two previous patterns involved a lot of movement so it felt very odd to me to stop like that. If you do this(I highly recommend it!!), make sure to move (9) too.
00:24:503 (5,6,7,8,9) - This is basically covered up by the previous pattern making it very hard to see. I'd suggest moving it over.
00:53:903 (9,10) - (9)'s slider end should point upwards and (10)'s slider end should point downwards. Basically, just switch them around.

01:21:503 (1) - Add a break here or add some notes. Killer HP drain section
01:56:303 (5,6,7,8) - This pattern doesn't play well. Make it more like (1,2,3,4). It'd feel a lot better.
02:17:228 (5,6,7,8,9,10,11,12,13) - Same case as before -- this streamer doesn't fit well.
02:51:953 (1) - Mini slider streams like these aren't very good. Instead, replace (1) with two hit notes.
03:00:428 (5,6,7,8,9,10,11,12,13) - Since these come up a lot, you may be reluctant to get rid of these, so let me explain further: these streams are overmapped.
Hard:
00:29:153 (3) - move this back two ticks and make it longer by two ticks
01:05:903 (3,4,5) - Not a fan of this small pattern. It feels weird the way they are placed. Perhaps consider a more triangular shape?
01:07:103 (3,4,5) - Same case
01:19:703 (1,2,3,4,5) - I suggest spreading these out more
01:42:653 (5) - Add a hit circle
01:57:053 (5) - ^
03:06:503 (1,2,3,4,5) - Spread these out more
