00:10:276 (4,1) - this overlap, unlike 00:06:889 (1,2) - , looks almost fully overlapeed which it might go against the rules of the game. would space a bit more to make more visible the next slider under the last note
same as 01:01:083 (1,2) - 01:15:276 (1,2) -
00:14:308 (5) - would make this 3/4 slider in double circle as did on 00:13:663 (2,3) - since you're following a similar rhythm
00:24:550 (4,5) - Objects 1/2 of a beat apart or less must not fully overlap. try make a stack instead
00:32:696 (1,2,3) - 00:21:889 (3,4,5) - vs 00:18:018 (3,4) - 00:20:599 (3,4) - etc. they are the same stack but one is triple 1/2 and another one is a double, they are hitted in a very short time from each other and they would be changed in a different pattern.
00:52:212 (2,3,4) this one also kinda questionable since i couldn't get what's 1/4 rhythm for cuz it sounds like a simple 1/2 rhythm
01:16:244 (5,6) - This is a jump and it's too much for a hard, it needs a nerf, maybe a 1.5 ds?
01:16:244 (5,6) - this jump, outside the other density jumps, looks quite distant for a hard diff which you reach a such spacing over of 2.00x. Consider to decrease the density spacing here and make similar jumps like 01:08:179 (5,6) -
