Don't get the reason to use tick rate 2, especially in Hard, it sounds just poor. (and you didn't use tick sounds as always, also if you reduce tick rate, scores would be lower and you could create more thing in that diff.)
[Easy]
01:03:280 (1,2,3,4,5) - make it curve better?
http://puu.sh/euaD01:49:967 (2) - as it's the easiest diff i still hope only 1/2 here. yes it's still just hold there, but i don't think a massive 1/4 strike during lots of 1/1 or longer notes is a good idea.
02:03:280 (1) - a suggestion here: add another reversed 1/2 slider at 02:05:155, then a 3/2 reversed slider at 02:06:280. now it sounds/plays kinda boring.
02:17:530 - add a note?
02:18:280 (1,2,3,4) - same thing as 01:03:280 (1,2,3,4,5)
03:09:280 (1) - no. i guess you just want to make the break not that long, but the spinner here itself is tiring enough. map something until 03:15:280 (as there's an obvious sound) then start the spinner plz?
04:00:280 (1,2,3,4) - same thing again.
04:24:280 - give a stop line for the kiai.
[Normal]
AR+1 if possible.
00:50:155 (4) - move it 1/2 later? (whistle, as you did in other parts.)
00:59:342 & 00:59:905 - just to make sure you don't like the beats here.
01:12:655 (3) - whistle at the reverse? (it won't blend with the clap much?)
02:06:280 (1,2,3) - feel a little boring here,
http://puu.sh/eugX ?
02:14:342 (4,5,6) - seems more consistent to me.
http://puu.sh/euht02:27:655 (3) - same whistle.
03:09:280 (1) - same as Easy.
03:45:092 (1) - ...could you draw it better..? i noticed you tend to use 3-point sliders. it curves not that good in some situation like this (at least to me, won't mention this again.)
04:09:655 (3) - whistle at the reverse.
04:24:280 - end of kiai.
[Hard]
i don't get why AR9 is used here. it doesn't fit at all imo. (160BPM, not so fast map)
01:22:405 (5) - touches HP bar.
02:06:280 (1) - still feels boring here but in such a diff don't know a way to change.
02:29:155 (2) -
http://puu.sh/eul1 ? don't like current beats.
02:10:030 (2,3,4,5) - maybe try to avoid patterns like this (large spacing notes in a line), i'm pretty sure most of the players don't like this and it could easily change to other placements. (won't mention again)
02:39:280 (1) - auto can only get 1000 on this spinner and in this point i don't think it's really needed to add such a short spinner. consider a slider or something else (or at least, make the spinner start 1/4 earlier and auto can get 2000)
03:58:967 (1,2) - switch the place of circle-slider. reason is quite obvious i think.
04:11:155 (2,3,4,5,6,7) - same thing. don't get it.
literally, get some more mods then call me to recheck.
