I will mod the hard
I hope I can find anything since this has been modded quite a few times.
I have no clue about any more tags, I think these are kinda enough, and I suck at hitsounds so I won't be able to mod those either (but I am trying to learn some more stuff)
so, here we go
Hard
00:46:983 (4) - curve for more flow
01:06:472 (3) - place it a little bit off the previous note so the player knows that it is an antijump for sure
01:39:976 (4,1) - I think this overlap can be made better or be removed, since now it looks just unfinished
02:22:238 (5) - I suggest placing this note a bit higher/more to the right so the pattern flows into the slider
02:51:581 (4) - this one feels out of place, I think it should be either a lot higher or a lot more to the left, or stack it, since it would also feel a lot better
02:53:114 (4) - curve please, unless you want symmetry with the previous slider, if that is the case, I'm fine with this
02:55:304 (4) - higher anchor point more to the right
03:31:654 (3) - curve or lower anchor point more to the left
03:36:910 (1) - maybe lower sv even more for a more dramatic effect
03:51:143 (4) - more to the left
04:46:326 (2) - lower please
01:06:472 (3) - place it a little bit off the previous note so the player knows that it is an antijump for sure
01:39:976 (4,1) - I think this overlap can be made better or be removed, since now it looks just unfinished
02:22:238 (5) - I suggest placing this note a bit higher/more to the right so the pattern flows into the slider
02:51:581 (4) - this one feels out of place, I think it should be either a lot higher or a lot more to the left, or stack it, since it would also feel a lot better

03:51:143 (4) - more to the left
04:46:326 (2) - lower please
Apart from some minor flow and random note placement, this map is really good, and if you get 4-5 more mods I think you are ready to call a BN
