I echo the “good work” sentiment from Ben. My sense is that generally the voice leading works well, and I enjoy the tonal shifting. I’m asking myself how this will play with singers. My own sense is that congregationally it will be a stretch; it has a more choral sound to me. As Ben mentioned, the sense of meter is a bit unstable — which adds interest but makes it more difficult to sing. It has a similar tonal ambiguity, which again will make it tougher to access for the average congregation. I think that is particularly true on the last system, where the key ambiguity barely gets resolved (to my ear) by the cadence. This is particularly true, I suppose, with the soprano ending on the dominant. My hunch is that have significant ambiguity in both the meter and the key will be a hurdle for singers.
I agree with you about getting it in front of singers, and see how it actually works for them. It might settle in more quickly than I think.
