Nice! I definitely get a baroque dance feel from this piece. The melodies are nice and catchy and you develop the motives very well.
I think it works fine. An alternative I thought of would be to use the below motive in some kind of cadential form, since it's so important throughout the piece. Perhaps instead of the descending scale at m.64, insert this motive and end on the tonic? Another idea would be to end on a picardy third, since the piece has been solidly minor throughout.
I also really like your counterpoint, you do a really good job passing the motives between voices and keeping each part independent and interesting. There are a couple spots, like m.11 and m.15 where the 1st Violins and Cellos move in seconds, but these happen pretty quick and are hard to notice.
The only question I have is on the bass notes in m.51 and 53. In m.51 the violins and viola seem to imply a C major chord, but the cello and bass are playing F on the downbeat, would it make sense to have the low voices play C instead? Likewise in m.53 the upper strings seem to imply Bb minor (or maybe G dim?) so maybe have the cello and bass play Bb on the downbeat? This would also allow the bass to ascend chromatically from m.53-55.
Is the playback directly from your notation software, or did you use a DAW? They sound a little dry to me, I think a small amount of reverb and maybe some panning would make it sound even better.
Thanks for sharing! The only thing I might add is some harpsichord, but maybe that's just me 🙂
