00:14:071 (14071|0) - What's the sound you picked there? if you pick harp sounds there,
why not also picked at 00:18:871? I suggested that try to make them same to make the picking balance and easy to catch.
00:42:571 ~ 00:48:867 - This part is too hard for just beginner player.I believe that it's a challenge for a player who play music game not for a long time to catch two different sounds at the same time. try to give up a picked-sound to make the mapset easier.if you think the difficult is resonable, at least delete 00:47:521 (47521|1) since it's too difficult to do three things(release 4 column's key,click 2 column's key,and focus 2 column's key) just in 1/4 snap, in easy mode.
01:15:721 - As you decided to pick flute sound there, you should pick all the not in this part so that it's not make the player in a mess. or you should try to use another way to arrange your note to pick the sound.

00:16:171 (16171|0,16321|2,16471|1) - rearrangement a little to make there click more comfortable.
So since the sound in 00:16:171 and 00:16:471 is totally same both volume and pitch,i think there should be considerate equally. and put 00:16:321 (16321|2) in column 1 can present the sound pitch's higher, becasue it make up a stair with 00:15:871 (15871|2,16021|1).
00:43:471 - Since you pick durm sound's on 00:43:171 (43171|1,43771|1), I think you should also pick durm sounds there.
00:45:871 , 00:48:271 - Same as above.
01:15:271 ~ 01:16:471 - You can use stair here like you did in HD difficult, to make the flute sounds picked balance.
01:21:271 - I think there can add a note in column 1 in order to make a stress about the background sound. also, a new part begin.
01:29:671 (89671|0,89971|3,90271|2,90571|1) - this part is more eaiser than EZ difficult
. you can try to use a harder arrangement.
01:49:396 - add notes in column 2,3 since you have follow Gong's sound like 01:49:171 and 01:49:621.
[4K HD]
00:18:871 - add a note that make equally stress with 00:18:271 (18271|1,18271|2,18571|0,18571|1).
00:23:821 (23821|2) - move to column 4. Since the cymbals's sound is not same as harp's sound, maybe not to make them to a group (stair) is a better choice, because it's more eaiser to let player understand the mapset, and know this time should catch two different sound. consider to let the player more comfortable to hit, you can keep it as it used to be.
00:38:446 - add a note to keep the equally picked sound.
4K MX is too hard that i can't controll correctly ;w;
