01:21:036 - 01:30:619 my main concern for this part is that the 1/4 dashes you made is a bit too far which requires too much precision for newer players, i highly recommend you to reduce the distances between the 1/4 dashes
same applies to the 1/4 dashes you did on some parts of the diff
Toned down 1/4 dashes here to x2.9
Applied the same on 00:56:036 - 01:19:161
