Yes, I agree with Lyndon. This is a very nice melody and the open 4ths and 5ths throughout fit the mood well! I think the main thing that bothered me in 11, 12 was the downbeat of 12. Maybe consider keeping the bass on the do and moving tenor up the the mi on beat 1… I also felt like the music lost some momentum in m. 5 with the dotted-half note. I will attach an image of a possible change.
I wasn’t sure what I thought about the voice overlap in m. 10 between tenor and bass and 15, between alto and soprano. But I don’t think about the one in 15 as much, and I kind of like how it feels in 10, so don’t take that too seriously. Solid work here, Lynn. I don’t feel super qualified to be doing this, so take it all with a grain of salt. thanks for sharing this!
