I understand that you're trying to follow the melody better with these notes, but I think having this kind of triplets in only red ticks isn't very good for a kantan diff. It's not wrong, it's just pretty risky.
What I recommend would be:
Move the 3 triplets 1/2 forward to bring them to the white ticks
Move this note 00:18:115 (18) 1/1 forward so here 00:18:532 to make the pattern a quintuplet
yeah i changed the rhythm it also had some inconsistencies with the finishers on the other diffs ty
