Hi there!
Without seeing the print music, I can't give a complete answer. But just reading the braille, I don't know why you've divided measure 50. Usually only the left hand would be divided to align with the chord symbols, and it doesn't appear to need a division here.
If you choose to use the bar lines, you don't technically need the dot 5 hyphen as well.
If you can send me an image of the print measures, I can more accurately answer this!
Thanks!
Kathleen
