*2 seconds audio lead-in seems a bit long. Perhaps change it to 1.5 or 1?

01:32:542 (1) - Appears before the previous note. How about starting this on the next blue tick and shortening like this:

00:32:370 (1,2,3,4) - I feel that these are a bit too tough for a Hard (especially at this high BPM). Perhaps remove one repeat from each?
01:10:301 (5,6) - ^
01:30:301 (9,10) - ^

*OD is too low for an Insane; please raise it one tick!
01:10:473 (6,1,1) - The kick slider is so short that it looks like an 1/8 and is really confusing. I suggest changing it to 1.0x speed, removing a repeat, and then fix the spacing to the next stream.
01:30:990 (1) - remove one repeat; 1/8 isn't enough reaction time between the end of the slider and the next note

01:30:990 (1) - same as Gold; remove one repeat
Lovely diff spread! I'll be happy to bubble this after these changes!
