Quick check. Great song, the skin is very pleasing to the eyes, and the map is solid all around.
[Insane]
00:15:621 (2) - Totally a nazi, but seeing as the rest of your sliders are pretty much beautiful, make this one less ugly.
00:39:445 (2) - You need to add a new combo here so that the spinner can end properly.
00:48:930 (6,1,2) - Despite that this is an insane, this stack is hard to read and is a miss waiting to happen. I'd unstack.
[Tiro Finale]
00:30:952 (2) - This doesn't follow your current beat placement pattern -- it's random. Remove it.
00:49:592 (5,6) - This is kind of a bastard stack. Technically, there's nothing wrong here but it's unpleasant to play ;_; I'd unstack it but do as you wish.
[Hard]
SPOILERYou -should- follow these, but if you don't want to ruin your patterns you don't have to.
00:35:033 (5) - The player won't be able to read that this slider 2 repeats -- it's the first of it's kind and it's slow. I'd suggest removing one of the repeats for intuitiveness.
00:50:916 (3) - Same thing. There's nothing hinting at the fact that the slider is going to have an extra repeat. Here's what I would do: remove one of the repeats, add a hit circle at 00:51:577 (4), stack it under the slider, and vertically flip 00:51:798 (5).
01:12:092 (6), 01:13:857 (5), 01:15:621 (3) - Again, not liking these repeats. I think you're better off with a single repeat.
01:20:033 (4) - Gah, another x-amount of repeats slider. This would work better as a long slider. Definitely change this.
