I agree with everything you've said here.
I decided to experiment with the MuseScore instruments simply because I was curious what the end result would look like. While I'm happy with this submission as a composition, I do feel the instruments don't quite do it justice, as others have mentioned. Hopefully in the future I can track this with live musicians or better sounding virtual strings. But for now, lesson learned.
I appreciate your comment, and thanks for listening :)
