As promised, here's a mod.
[General]
I thought the blue hitcircle colour blended with the background at times; maybe make it a hint lighter? Or just remove it? Doesn't matter though.
Still needs a preview point and a lower-bitrate MP3. Nag nag nag nag nag.
[All Difficulties]
01:28:479 - 01:34:479 - This part could be quieter. Very noticeable on Easy and Insane, although the change to soft hitsounds is fine by itself on Normal+.
[Easy]
00:51:354 (1,1) - A bit concerned about the lack of space here.
[Holoaz's Normal+]
Wasn't really hard enough to deserve the +, imo. A plain Normal should be okay, since you do have an easy in this mapset.
00:16:479 (1,2,3,4) - This diamond felt a bit...non-symmetrical, though I could just be crazy.
00:41:791 (4) - I'd take this out note and put it at 00:42:541 instead, since this combo seems to be accompanying the vocals rather than following them, so putting the extra note when the vocals aren't doing anything is good. But hey, not a big thing, very subjective.
00:28:666 (3) - Looking back, it's the same here as above, I personally would like that note at 00:27:916. Still, subjective thing.
00:49:666 (1,1,2,3) - I feel like you're missing the opportunity to really map something exciting in these two measures. I know it's a Normal (+), but this is such a mini-climax in the song. XD
00:55:666 (1) - There's a new combo here as well as at 01:45:354 (1), but 01:07:854 (4) - there's no new combo here. Just a minor inconsistency.
[Hard]
Ooh, streamy. That's fresh. Haven't played much of that lately. I'd be comfortable raising the approach rate by another tick here; on such a jumpy map, I think it'd make things easier, rather than harder. Some people might disagree though, so 7 is fine too.
01:41:041 (1,2,3,4,5) - This probably would be better properly spaced; it's not something I think people can get on their first play-through, although it becomes easy enough once you know it's there.
01:41:041 (1) - If you don't do the above, just slide the 1 down by a grid; it's not properly centered.
01:56:604 (1,2,3) - ^ I actually played through these parts twice in normal mode before heading to edit mode, and the first time I thought they were just 1/1, and the second time I thought they were 1/1, 1/1, 1/2. The hitsounds are a bit loud on these finishes too, I think, since they covered up what they were following, so even when I missed them, I didn't know where the note should have been.
01:59:604 (9) - A new combo here? Breaks up the long chain a bit, and has one combo for the rise and one combo for the fall.
Really artistic Hard, very visually pleasing.
Nag nag nag star nag nag nag.
