Wow...that was very pleasant to listen to. I'm playing this for the third time and it actually put my daughter to sleep while I played it hahaha. Once again and as usual the melodies you create are very beautiful and ongoing that fluctuates highs and lows that compliments each other elegantly. Good job!
1. Good in atmosphere, some executional problems. Clashing tones like in m. 28 with the G# and the A, and 39 with E naturals and E-sharps. While I can't say that I'm great at writing choral music, there's something to be said about it still following these conventions. I'm also curious by the ending on the dominant.
2. I'm not sure I quite understand this one harmonically. It seems to go all over the place. The interjections of fast tempo didn't feel quite justified in terms of setup and the slow sections made some weird harmonic choices I'm not sure what you were going for. Not to say all of them sounded off.
3. This is probably the most straightforward movement. I think my only gripe is sometimes you manage suspensions and retardations a little bit strangely.
4. Bowings in this one aren't as smooth. m. 7, leading tone always resolves up, same with other places. Lot more parallel fifths in this one as well. Also kind of an awkward end.
You found a nice way to make the chords in here work well with each other. The Neapolitan 2nd (the F major chord) and the iv chord complimented each other well and you switched between them really quite well.
My main issue is the rhythm of the melodic/harmonic line. A lot of the time it's incongruent with the main beat in places that don't really feel purposeful, like the middle of beats occasionally. Maybe it would have helped if the base beat changed to compliment this a little more.
