I feel like the one-hand trills ruins the orchestral part. It just doesn't seem right but I'm a 5 digit so I don't know anything
I get what you're trying to do with the trills by matching the music and interpreting how the 7K map did it, but the trills on 4k just don't look and feel right at all. I feel that a simple LN section would fit better than the trills. (Just a suggestion, I know nothing about mapping so correct me if I'm missing out on something)
