String quartet 1/I

This is a recording of the first movement of my first string quartet. The recording is from the dress rehearsal. I composed this five years ago. (I posted the second movement a couple of weeks ago.

It's nice. It's cool how the atmosphere remains even with different sections in it.
It's a little lonely sounding to have the first violin play along with rhythms for so long. I get that it's probably intentional, but it stood out to me.
I'm curious as to why you put grace note pizzicatos in a section that's so quick too. It certainly doesn't sound as if it were performed as written.
But you know what you're doing. Great job!
