Shana's Class:
00:06:911 (6) - New combo
00:11:002 (6,7) - I'd recommend spacing these out the same as the rest of the notes in this section. Also, put a new combo on (7).
00:15:638 (5) - New combo
00:17:820 (10) - New combo
00:21:911 (4) - Too far from (3)

00:31:729 (3) - Too far from (2)
00:33:093 (7) - Too far from (6), and also new combo

01:23:275 (8) - New combo
While the map still needs a bit of work, it's definitely a lot nicer than it was before. Good job and good luck!
