[General]
i think volume is boring and should be more intoned
so i'd suggest to make kiai time louder or the rest quieter
[Easy]
pattern is too complex and there are a lot of 1.5 rhythm, they are hard for beginner
you should make them simple and constant in an easiest diff
for example;00:19:373 (1) - . you should move it to 1/2 earlier
00:28:348 - finish is too much, whistle is enough. also Insane doesnt have it.
00:41:681 (3,1) - switch these newcombos because of a downbeat
also stacking with different color looks bad to me. if you fix it, looks much better
01:05:527 (2) - compare with (3), i think (2) should be softer than (3) so remove whistle
01:09:886 - clap is better here, also no need to reduce volume
01:10:399 (1,2,3,4) - i think this pattern is hard to read for beginner, but maybe it's just me.
01:10:912 (2,4) - finishes are too much, and whistle sounds better
01:12:194 (1) - after continuity of 1/1 rhythm, you should not use 1/2 rhythm suddenly
beginner wont be able to get rhythm well so try something like these to solve it

01:14:502 (4) - add finish here, insane has it.
01:21:168 - listen music carefully, percussion sounds on 01:21:040 - and 01:21:425 - .
so try this instead
http://puu.sh/wPlHat least you should remove clap from (1)'s end. it really sounds bad
01:22:707 (3,1) - switch these newcombos because of a downbeat? it also matches music better
01:33:989 - finish is too loud. whistle is better
01:34:373 - remove whistle, it follows nothing and sounds not good.
01:36:809 - ^
01:39:117 (1) - <3
01:50:912 - clap is better here imo
01:51:425 (1,2,3,4) - same as previous one
02:02:963 (2) - try to remove whistle from the beginning, it'll sound better to me :3
02:07:322 - add clap instead of whistle
02:08:348 (2,4) - whistle is enough for these notes
02:46:809 (1) - start this at 02:47:066 - ? it will fit vocal better but just sugesstion
03:02:963 (1,2,3,4,5,1) -
consider simplifying them it's really hard
try something like this instead i think it's enough

03:05:271 (1) - it would be better to avoid using 0.5x slider especially in an easiest diff
this slider looks same as 1.0x one so it may be confusing for beginner
03:12:707 (2) - remove whistle from the beginning
03:35:784 (2) - curve this slider a bit for better flow?
[Hardiers]
AR-1~2. too fast for such a low BPM
00:17:066 (1) - add finish? i can hear it clearly in the music
00:22:707 - add note and clap
00:25:271 (1) - add finish
00:32:963 (5) - add finish at the end? just suggestion
00:35:527 - finish doesnt fit here
00:27:322 (1,2) - it'll look better if the spacing between (1) and (2)'s end looks same as the normal spacing(0.8x)
http://puu.sh/wPvj00:44:245 (2) - add clap to this note? i guess you forget to put it
00:49:373 (5) - add finish at the end
00:56:681 - add note here? just suggestion
01:05:656 (7) - remove clap please, it doesnt fit here. if you'd like to put it somewhere, 01:05:784 - is better
01:20:655 (1) - add clap at the end?
01:21:425 (4) - ^
01:46:681 (5) - same as 01:05:656 (7) - . i's suggest to add note and clap at 01:46:809 -
02:09:886 (6,7) - i think this pattern looks bad and hard to read ;w;
02:11:168 (1) - this is still rankable, but it is too short and doesnt fit here
i suggest to remove it and remap here
02:20:143 (1) - mute this spinner's end or delete note at 02:23:220 - and extend spinner to there
02:29:886 (1) - remove whistle from the end add it to (2)? i think it sounds better
03:30:399 (4,5) - how about making them symmentrical like this? :3
http://puu.sh/wPEo[Insane]
00:27:963 (4,5) - it'll be look much better if (4) perfectly overlaps over (5)'s slider path
http://puu.sh/wPFs00:44:502 - add note here or add repeat to previous slider?
00:56:040 (5) - add clap at the end
01:09:886 (5) - add clap at the beginning? just suggestion
01:18:604 - add note
01:29:373 (2) - clap is better than whistle imo
01:37:963 - add note to follow music better
02:36:297 (2,3) - add newcombos like you did at 02:33:989 (1,1,1) - ?
01:44:245 (6,7) - i prefer stacking the end of them perfectly
02:42:066 (5) - remove whistle from the beginning, because it follows nothing
02:43:732 (5) - ^ from repeat of this
02:46:168 (4) - ^
02:47:835 (3) - increase volume step by step? it sounds really nice
that's all, good luck!
EDIT: contact me after adding Normal diff, i'll give you some suggestion :3
