While it will be more consistent with the instruments being represented, the overall difficulty of the song would be pretty hard. I feel like there needs to be a bit of a 'cool off' section right after 00:09:600 to 00:14:400 . The music is also much less intense than earlier sections so I feel that leaving the notes out will help emphasise the earlier sections much better.
Another thing; move these notes to another col (I recommend move to col9) because of different pitch compare to 00:29:400 (29400|0) - note.
The LNs were for the strings, not the piano streams. Will keep them as single notes. I did move 00:30:000 (30000|1) - to column 6 for the pitch thing
