Alrighty then.
[General]
Timing is pretty bad, but as discussed in IRC you'll be tightening it up. Don't forget about all those unsnapped slider ends and stuff.
Consider using a light grey sliderborder color to go with the hitcircle overlay? Looks kind of weird otherwise due to all the transparency

Tick rate 2 fits this song best.
[Normal]
01:49:392 (1) - A little soon after a spinner for a Normal. Kind of borderline on this one.
02:10:853 (1) - This one, not so much. Way too soon after a spinner.
02:10:853 (1) - ^
02:16:392 (1) - Why not just extend this to 02:18:238 - ?
02:35:776 (3,4) - Hm, think you could try something different here? This is kind of a lower-level Normal difficulty, and stacking 1/2 onto a 1/2 slider might be a little difficult to read well, then following up after that short slider into another hit object 1/2 away.
02:43:161 (2,3) - Same thing here
02:45:468 (4,1) - I wouldn't mind this spacing as much if the 1 wasn't on the screen when the 4 slider was finished. As it is, it feels way too close.
03:02:545 (1) - Too soon after a spinner
03:09:007 (3,4) - You know, you could just simplify rhythms instead of trying to hit every note. This -is- a Normal, after all. Try to reduce your 1/2 rhythm usage a little.
04:02:625 (1) - Again, a little soon after a spinner. At least move this closer to the center to aid in recovery.
[Hard]
There's a lot of completely silent hit objects here. Add some audible sounds to them please.
Check for consistent use of sliderslides too.
01:01:836 (1,2) - I kind of had a hard time telling this was a slider -> circle at first glance.
01:56:776 (2,1) - Veeeery tiny overlap here. Think you can move it slightly away?

02:36:699 (4,8,3) - Add finish?
02:40:392 (4,3) - Add finish
02:43:622 (2,2,4) - Add finish?
03:24:238 (4) - This stacked note feels like it kills all that momentum you had with the rest of the chorus.
03:28:392 (1) - Another flow-killing stack
03:32:084 (1) - It'd be cool if you started adding more of the custom hitsound usage here to help accentuate the SB and the final round of the chorus.
[Insane]
There are occasional completely silent notes scattered about this difficulty too.
01:33:930 (1) - This slow slider intentional? It doesn't feel right considering you go right to full speed here 01:35:776 (1) -
01:41:315 (1) - Another awkward slow slider transition compared with 01:43:161 (1) -
02:56:776 - Missing a SB hitsound?
03:13:622 (1,1,1) - New combo spaaaaam
03:38:084 (1,2) - These play awkwardly. Usually sliders in streams work best in multiples of 2, not 3.
03:44:084 (2,1) - After those two grandly spaced sliders, I was expecting the pattern afterward to be a bit further away than this.
[Taiko]
The beginning feels way too dense note-wise. Hold back a bit. It feels like you're driving a bulldozer through the calm forest.
The ending feels like you're beating the drums unnecessarily as well considering the instrumentation. Maybe considering starting the map later and ending it early?
