Hi Nymph here and request from ingame.
General:
nothing found here.
Easy:
Hitsound
00:06:362 (1) - actually I am not a fun for using the hitsounds like this. you see, you got 2 whistle here: 00:05:336 (5), and now you got a 3rd whistle on the head of this slider, it just feel like the rhythm is connecting, but actually it is not. so I didn't feel good on this. not a big issue, just my personall suggestion.
00:14:567 (1) - ^ so same things like this I am not gonna mention again.
00:28:926 (3) - I don't get it why 2 whistles here, it just didn't feel very consistent, any particular reason? I think it is better to delete the whistle on the arrow.
00:49:439 (1) - also same as I said in 00:06:362, whistles would be very nice instead of finish, I think 4 whistles after here is a pretty good idea.
nothing wrong really, I just prefer consistent hitsounds.
Normal:
Beatmap design/suggestion
00:33:029 (4,5) - feel a little weird about this pattern at first, but I guess it is fine.
00:55:080 (4) - I think it would be more interesting and look better if 4 didn't stack with 123, just suggestion.
Hitsound
01:03:542 (6) - this whistle feel pretty weird and sudden, I suggest to remove it.
Hard:
Beatmap design/suggestion
00:53:798 (1,2,3,4) - hard diff I suggest to use these note make a square or something, not just stack them, not very fun imo.
Vicho's Insane:
Hitsound
01:15:849 (1) - maybe a finish on the tail of this slider? feel a little empty there.
others fine for me.
I guess that's all. Actually I think the whistles could be more consistent, but not sure if you like that.So I am not gonna give further suggestions on those.
good luck then~
