00:04:850 (3,1,2,3,4,1) - too crowded
separate them or replace 00:05:975 (2) - with circle and move 00:06:350 (3,4,1) - a little further
that timestamp is pointing at a circle?? 00:05:975 (2)
and 00:06:350 (3,4,1) already is spaced away from it
00:07:565 (1,2) - maybe replace these objects, like this? https://osu.ppy.sh/ss/17782908/2a21
00:19:850 (2,1) - not a good situation here
pick either stack 2 circles with 1/2 beat gap or 2 circles with 1 beat gap
don't use both or use neither (if you wanna buff the SR)
00:21:440 (1,1,1) - there should be at least 2,3 beats between a spinner's end and next object
00:24:725 (1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4) - too many consecutive 1/2 beat gaps. leave at least 1 beat gap each 2 measures to provide new players a recipe of reading
2 measures of continuous 1/2 beat are too dense for norma
00:53:037 (4,2) - not a good stack situation here.move 00:53:975 (2) - somewhere else like01:05:037 (4,2)
