I liked it a lot! It reminded me of George Crumb's Black Angels (m. 31 reminded me of Devil Music) The only thing I could say would minimally improve it (Don't bite me, please, this is really the most minimal of things) would be to utilize silence more.
In the score the piano parts don't really contrast with the forte sections. I would say it was a performance error, but as the violinists seem so virtuostic, maybe you just need to consider. Since I compared you to Crumb, one of my favorite composers, already, you should know that one of the things I love the most about his works is the silence that contrasts with the insanity and confusion. Please don't take this negativly in the least bit, I admire you so much, and I'm looking forward to seeing your name in concert programs in the near future.
