Sounds good! Some interesting chords there, including at the opening. Even though its a short piece, I think you could have more interesting textures, e.g. Violin 2 taking the melody over 1, or the cello doing something gorgeous in its upper register (there are some attempts made in this manner, but it would make for more engaging music to go further and expand the texture a bit beyond Violin 1 at the top, 2 underneath, viola underneath, and cello at the bottom). Also, in bar 18 for example, there is duplication of notes leading to a thin texture where there could be a richer, more full one: the viola plays a C#, the same as in Violin 1, then a B, which is the same as in Violin 2, so the melody there is indistinct and obscured (though the decision to place the melody in the viola is a nice one). My personal taste is also that pandiatonic music isn't as interesting as when there are interesting modulations and changes of mode, but this is a fine example of the expressive aspect of pandiatonicism. Thanks for posting!
