00:02:681 (3,1) - this goes for all such patterns like this. You have a really hard map, but you have empty spaces like this that would be okay for a normal - hard diff. Anything above, you would generally fill this with a slider or something. That makes the map feel like parts of it don't fit well with the rest - a.k.a. you have 7* jumps but 3* note placement, i dont know if im explaining myself very well. I'd fill this with a slider. Also, an empty space and then a spaced triple feels uncomfortable to play.
00:29:006 (3) - all triples like this one are overmapped, i don't hear anything on this blue tick. Ill give examples 00:21:806 (3) - 00:23:006 (3) - 00:24:206 (3) -
00:12:581 (1,2) - I think all triples like this one could be less spaced. It doesn't fit very well with the music, they arent like super drum bursts, just normal snare triples
Some of your slider feel so awkward when the slider start is quiet and the tail is loud like 00:44:231 (1) - Avoid them. You should keep the slider end not louder than the head, because no one want to lift their finger on a noticeable sound.
it's not about the volume, but about the feel. If you try to follow the volume bu active and passive clicks, you will end up with a mess. upbeat/kick is noticably stronger than an even louder, but downbeat snare.
At the beginning i aslo thought that snare needs to be active, but it felt "wrong", so i mapped it like that
Could maybe try to follow little of those 1/2 guitar parts in the kiais aka stuff like at 01:59:831 (1) - for example (basically the parts that differ from the normal) so it'd bring some occasional variation to the otherwise quite well-repeated structure
