I like how you used the sustained violins, floating on top, to contrast against the ostinato bubbling underneath, and I also like the galloping rhythm at 1:44. Was this piece inspired by minimalist composers? One of my favorite pieces in this style and in general is Philip Glass’s String Quartet no. 5, especially the 3rd movement—it’s worth checking out! Your music effectively conveys that sense of urgency and desperation, so good work with this piece!
