Bravo!
I definitely heard Chopin Ballade in G minor at the opening there! Wonderful piece through and through, I especially loved the first few minutes. You've got such a great command of the strings. The textures were full but I was able to hear each part clearly.
I would've loved to hear a breif recap of the opening material at the end before your final chord- I think that would've tied the entire piece together more thoroughly. Just nit-picking things, what you have now works as well :)
Great work, I can't wait to hear more!
