Nicely done. I recall reading something about (or maybe by) Paul Hindemith to the effect that he used consonant chords as momentary "points of repose" within a more unstable movement, and I hear a similar kind of thing here.
If you want a suggestion, I'd say eliminate the tremolo in the strings (that is, just bow normally) in bars 18 - 23. Also, production-wise, your horns are too far in the distance.
And it looks like the score doesn't quite match the audio version, so if you feel like posting a score update that may garner some more detailed comments.
