Also, I just wanted to note that I recognize that the quad-tuple measures are a little strange. If I could, I'd have done those measures in 4/4, but the musescore app makes it difficult to have one part in 4/4 and the others remaining in 12/8. So, quad-tuples were the better option, I felt; otherwise the other parts would switch from 12/8 to suddenly having a lot of triplet figures in 4/4.
