00:31:956 - kinda weird how you're ignoring this sound and not making it active as you begin to follow it with 00:31:304 (1,2) -
would be more logical to continue following it since it's quite strong here, so i suggest reducing 00:31:793 (3) - to 00:31:874 - and having a new 1/4 starting 00:31:956 - that you could repeat until 00:32:200 -
i told you what i think with my suggestion, it makes no sense since the exact same sound was mapped already as circles (00:27:391 (1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8) - 00:29:999 (1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8) - ) so it only makes sense to continue using circles to map that same sound, nothing has been added to it to make it distinct from the first two patterns.
if you wish to make it more intense than the first two patterns, to show some progress in a way, you can always make the stream itself more intense by having bigger spacing between circles, etc.
00:49:565 (1) - i think spacing here should be increased to better emphasize this sound, you are coming out of a pretty easy slider section with a relatively slow last sv slider at the end yet spacing is significantly lower than something like 00:50:706 (6,1) - which makes this slider feel underwhelming when it should be a highly emphasized note for the player
