This is obviously not piano music, beyond that, I had a listen and enjoyed the first movement. It sounds classical enough, and worked at several levels, despite the reverb and the phony sounding fiddle. I take it this was an electronic simulation? It would be great if you could ask an orchestra/chamber group to play it. The instrument solos at :48, 1:58, 2:51, 4:23, 5:18 were nice.
Were you thinking of arranging this to piano?
Perhaps you would try 3 pianos, 12 hands. Of course, the vibrato effect that string players can produce would not work on the piano..
