Anything about the book of Matthew, I love it. Critiques. This could be..and probably should be done with traditional String Quartet. Odd instrumentations tend to not get played. String Quartets ALWAYS get played. 24-7, 365; a string quartets are playing somewhere.. The arco might not be feasible in meas. 2. You may need to take out the E5 on the "e of 4" to make that arco happen. Also, I know you want it short, but....the rule of thumb for typesetting is don't use rests whenever necessary. SO, perhaps write the cello with eighth notes instead. It's just a cleaner look and easier to read. The equivalent would be writing you reading this sentence with all this space. It can come off as real gratuitous, convoluted. and byzantine.
