01:22:366 (3) / 02:50:699 (2) You could make this slider reverse longer, so he goes to the blue tick. (as u did at 03:16:353 (1)) This will not make the map very harder and will follow more the main theme.
At 01:22:366 (3) / 02:50:699 (2) these go at 1/4 beat snap divisor. Since this is a hard difficulty I give the players more time to react when it ends on the red tick. At 03:16:353 (1) the beat snap divisor is 1/3 and I assesed that a 1/3 beat would be enough time to react. Therefore, no change.
01:45:329 (19,20) - this could be represented with a slider instead since its a held sound. also NC at 19
01:45:699 (14) - unreadable for a beginner who play 3*, due to the change of rhythm and no change in spacing (overlapped)
01:51:255 (19) - similar to here 01:45:329 (19,20) but instead of slider tail at 20, having it end on 01:51:820 would fit vocals
01:57:551 (5) - Similar problem of spacing here. It have the same spacing as 01:58:107 (2,3,4) but the rhythm is 2 time longer.
I would argue that the new combo signifies change in the upcoming circles. Furthermore, the guitar and drums have distinctive sounds here 01:58:292 (3,4,5) - . For now, no change^^
02:24:588 (1) - Maybe it should have a larger spacing compare to 02:23:847 (5) due to the breack of rythms. (It should be the double spacing of this 2 note : 02:24:588 (1,2))
I tried fixing it, but it created a lesser aesthetical overlap (if I so say). I think this works, but let me know if I should redo. Otherwise if you have any idea as to how you would place 02:24:588 (1,2,3) - feel free to reopen.
