00:09:087 (17,18,19,20,21) - This section contains pitch changes, you should consider changing it to kd d k k
changed the pattern kk k k k to kd k k k
there's (almost) same pattern on 00:03:157 (1,2,3,4,5,6) and the 3rd note in that pattern is already represented as k, so I think kd k k k is more proper
00:50:598 (1) - Similar issue to kantan, you should extend this spinner to 00:51:645 -
