Overall, nice work. You have a fine skill at avoiding parallel intervals by inverting chords. ‘Corinthians’ is misspelled in the subtitle.
All following comments come from a bass’s perspective.
Basses will appreciate a slightly lower tessitura throughout this piece. Here are four places that could be modified to suit that goal:
1. In the second measure, it will be much easier for the bass to drop to the la instead of jumping up the sixth. From there, bass can sit on the so until measure 4.
2. At the end of measure 14, bass again leaps up a sixth. I would recommend that bass instead drop to the re.
3. In measures 7 and 8, take the so down an octave. Many basses will drop the octave anyway in congregational singing. (Flat A’s are just uncomfortable to sing for more than a measure.) Lead into that octave with a passing la in measure 6.
4. In measure 15, try taking the second so down an octave. That will really make the basses feel courageous as they cruise in from the higher notes.
