Hi @user011235!
You wrote it in 4 days?! That's kind of amazing.
Speakng of the music, I for sure like the classical/early romantic style of the music. The modulations are wonderful too.
For me maybe you can add much more slurs to both instruments especially the violin, since I think it won't play that much notes without legatos even under styles, especially in expressive spots like b.316! Also, the very high pitched pizzicato, like in b.203, sometimes sounds a bit uneffective for me, as they sounds really spicy and disappears really quickly.
Thx for sharing!
Henry
