[General]*Even though four of the difficulties start right at the beginning of the map, I really don't see a need for an audio lead-in. There's already two seconds of silence before the notes, and so adding a lead-in of 2 1/2 additional seconds is just overkill. If anything, change them to 0.5 seconds, but definitely nothing more.
*I'm surprised that Hard/Insane/Extra use 1.4 SV, while the guest Hard uses 1.6, but it's an issue, per se. I suggest using faster SVs for the hardest difficulties in the future, though!
[Timing]*Uninherited section at 00:55:645 is unnecessary; remove and resnap notes!
*Uninherited section at 01:56:978 is unnecessary; remove and resnap notes!
[Rust]00:54:306 (1) - Isn't snapped to the white tick (regardless of the uninherited section there).
[Bronze]*Difficulty settings felt a bit low; I'd bump up the Drain and OD by 1 tick each.
00:08:973 (3) - love sliders like this
00:31:723 (1) - Since the approach late is a bit low, I'd move this to the red tick and shorten by 1/4.
[Silver]01:22:311 (5) - Perhaps new combo this?
01:48:478 (1,2) - Try and make these closer since (2) is only 1/2 after (1). Otherwise, they look more like 01:49:478 (2,3) which have a 1/1 space in-between...
[Emdyion's Silver]*Check AIMod for unsnapped notes, even though you'll need to resnap after removing the aforementioned uninherited sections.
01:36:478 (1) - perhaps add a finish?
[Gold]*I'd bump the Drain/OD up by 1 tick each; this IS an "Insane", after all. :p
[Platinum]00:32:973 (1,2,3,4,5,6,7,8,9) - looove these jumps~
02:07:644 (1) - This is unrankable, since the slider path is very ambiguous (especially when using mmsliders:
