insane should probably be cs 4, having two cs 5s and then a random cs 3 is weird as hell

general
- disable widescreen support on easy and extra
while not a huge issue you can probably make easy and normal end on 01:54:490 - like every other diff
as for general tips for mapping:
you don't have to use grid snap (actually most people map without it for every diff) since it leads to distance snapping being buggy in most instances + looks aesthetically ugly 90% of the time
from just glancing over extra it seems like you use distance snap too frequently as well -- distance snap is usually only used in easy and normal diffs (sometimes hard but that depends on a lot of things); if you distance snap everything in an extra you get a lack of emphasis on a lot of notes which is apparent throughout the diff
- od 8 would be better here, having insane at od 7 and the extra is weird
not going into aesthetics too much, but 00:02:740 (3) - stuff like this is really weird if you're going for a fully symmetrical / linear pattern; it suddenly curves up for no apparent reason compared to the rest of the pattern
00:07:802 (4,5,6) - these triples aren't triples, 00:07:802 (4,5) - there's a 1/8 note in between these; i'd make the first two notes a 1/8 repeat instead, but what you have right now is fine
00:10:240 (2) - i'd just make this a normal curve and not a red node curve lol
00:13:240 (3) - clap / snare hit should be clickable here
00:23:365 (1,2,3,4,5) - for reference, instead of making patterns like this by hand you can make a polygon shape using compose > create polygon circles (ctrl+shift+d) and edit the shape to your liking to make a star or whatever you want basically
00:27:115 (3,4,5) - awkward rhythm introduction here, it goes from 1/1 to 3/4 suddenly but there's no visual indication in terms of spacing/patterning that it changes
00:38:740 - you're missing REALLY strong beats here by not mapping this lol, i'd recommend you relook through the map and add these beats as necessary
skipping a few
01:23:365 (1,2,3,4,1,2,3,4) - why so big of spacing tho
most of the issues i pointed about above go for basically the entire map; honestly in general the extra diff feels really unnecessary as the song doesn't really call for more than 4.5ish stars of mapping. everything else goes on the limit of overdone/overmapping. for a first for-rank map it definitely has potential but it'd need a lot more mods imo.
would mod more but i'd be repeating myself so yea lol
