[General]*Letterboxing looks kinda weird since it cuts off the top of Lily's head...
*Perhaps start the second kiai section at 01:20:684 instead?
*Use this spinner-background instead of your current one. That way, it'll be a nice/smooth transition from the normal bg to the spinner:
http://puu.sh/Q49*Since kiai affects the main menu, I suggest that the first kiai section end at the same spot on each difficulty. Either 00:30:764 or 00:32:684 would be a nice spot.
*Perhaps add a single kiai fountain at 02:39:404 since that's where most of the diffs end (and where a chorus would have been)?
And how about a kiai section from 03:25:484 to 03:40:844? That would put a fountain on the last note of Snow, and would look nice on the main menu (where kiai will show even if that part isn't mapped). If you want to, then add it to all diffs.
*Fix the score/default skin elements, of course.
[Easy]*End kiai at 01:36:044.
00:55:724 (1,2) - This sounds strange because the vocals/cymbal ends on the blue tick before (2). How about just making this a slider like:
http://puu.sh/Q2v The sliders after this have the same blue tick pattern, but it doesn't sound as awkward as these two single notes.
02:29:804 (1,2) - ^
[Neet's Normal]*Diff settings are a bit low, so perhaps raise Drain/OD 1 tick each (and maybe approach rate 1 tick as well)?
*SliderMultiplier:0.999999999999999 - weirdddd :p
01:00:524 (2) - Maybe move this back to the blue tick and extend?
http://puu.sh/Q68[Hard]*If you're going to have a kiai section at 03:02:444, then add it to the other difficulties as well (same reasons as up above with the main menu).
01:22:604 (1) - A bit hidden under 01:21:404 (2)'s hitburst (100/300/etc).
01:27:884 (6,1) - The overlap makes it look like 1 is only 1/4th of a beat after 6. Try fixing the spacing so that there's no overlap.
01:35:084 (1) - hidden under the previous hitbursts.
02:54:764 - Expected a note here.
[Snow]*I really do not like the AR 9 on this map. It just feels too tough and isn't very fun imo. I
really suggest lowering the approach rate one tick. If you do, then perhaps raise the OD/Drain one tick each since they would be a bit low.
*Tags:SnowWhite - Not a big deal, but why is white capitalized only on this diff? :p
00:55:484 (6,7) - The short slider makes this look like three 1/4 notes. How about stacking 6/7 like you did a couple of times before this?
00:56:444 (3,4,5) - Again, the short slider makes this pattern confusing.
01:36:044 - Expected a note here.
02:03:404 (4,5) - Maybe just make these into a single note stream?
02:39:125 (1,2,3,4) - Unsnapped? And these are hard to read/predict anyway. How about trying a 1/8th repeating slider like:
