00:07:059 (4,1) - should not overlap them cuz it would confuse new players at this 1/1 rhythm gap
according to guideline of normal diff:"Avoid overlapping circles, slider heads, and slider tails." except that's 1/2 distance snapping
00:15:064 (1,2,3,1) - this kind of overlap is really confusing for newer players and will cause for a lot of players to misread the pattern. I'd suggest to rearrange your pattern a bit to avoid this overla. Try something like this https://i.imgur.com/A4iE87X.png to make it more intuitive to read for newer players
00:23:516 (1,2,3) - just like your Hard Difficulty where you map vocal and drums first 00:20:773 (1,2,3,1,2,3) - and then suddenly ignore the drums switching to guitar.
I've made 00:23:516 (1) - to a repeat to at least make the transition smooth. Reopen this issue if it isn't enough.
00:37:007 (1,2,3,4,1) - this chain is really dense considering the songs intensity and leads to a disconnected gameplay experience. Nerfing the density of the rhythm would be ideal. Something like this could work https://i.imgur.com/PEm3hOT.png
