The difficulty gap between this and easy diff too distant. Normal is far mare dense than easy and more strenuous especially in 2nd kiai. There are basically no pauses for the player to recover. I suggest deleting notes such as 00:12:545 (12545|1) - 00:14:545 (14545|1) - 00:17:879 (17879|2) - 00:25:879 (25879|0) - etc.
00:10:712 - 00:21:379; have a very identical pattern with 00:34:712 - 00:44:712;
Consider changing the 1st kiai pattern to be a more complex one.
Example for 00:10:712: 
Making a forgivable 1/4 stream on the start. And removing the 2 chords to avoid burden new player.
Apply this to rest of the 1st kiai.
Some part is breaking ranking criteria rules. (1st and 2nd kiai and after it)
Long streams of 1/2 notes should include, at minimum, a 1/1 pause where natural to implement after every musical phrase, as these can become too physically demanding for players at this level.
Consider have a 1/1 pause every phrase of the song. (e.g. delete this note. 00:13:545; 00:16:212; 00:18:879; etc. 00:37:545; 00:40:212; etc.)
