Hiya!
I could only mod the Insane one, sorry, but I did my best.
Insane
00:08:075 (1) - A curved slider would fit better, since there's no noticeable change in the song;
00:13:896 (1,2) - Ctrl + G?
00:20:388 (3) - I think this is curved too much, reduce it a little;
00:27:105 (3) - Could be curved a bit more, to blanket better;
00:39:194 (3) - Move to x:250 y:196; (better overlap)
01:08:075 (4,5,6) - Should be mapped like 01:07:179 (1,2,3) for consistency;
02:12:552 - Potential for stream here;
02:21:731 (4) - Could be closer to 3, because 4 is of less intensity;
02:30:799 (6,7) - Move a bit lower, my OCD is triggering me;
02:44:231 (2,3) - Should be mapped like 02:42:440 (2,3) , or vice-versa;
02:51:731 (2,3,4,5) - Would fit better on the song like this
03:17:030 - Again, could be a stream here;
03:20:612 - Maybe a triplet?
03:40:313 (3,4,5) - Uneven spacing;
03:43:000 (3) - Hitcircle is offscreen a little;
04:28:224 (1,2) - Ctrl + G?
00:13:896 (1,2) - Ctrl + G?
