Alright, I'll try and comment on this as it goes:
Mvmt 1 : I like the ending... very eerie. I also appreciated your economy of material - The various motives stated at the very beginning were present throughout. I wouldn't repeat 59-73, frankly I think it gets too repetitive. I didn't like the transitions between one bout of thematic material and the next; even though we know the lines well already, I think the best thing to do would be to lead smoothly into each one. I was fascinated by the pizz. triplets for some unknown reason
Mvmt 2 : m. 182 was unneccessary in my opinion. The use of 5/4 was very interesting, it was a lot of fun to listen to. The little dissonances here and there really added to the flavour.
Mvmt 3: m. 262 - 263 , you have the cello above the first violin... it has a particular effect, but seeing as your cello parts are usually very high, I have to question that disposition. I feel a little bit like I did in the first Mvmt, namely, the same themes and motives are present throughout; but I sense a lack of unity... it renders the whole uninteresting, even if the harmony is as quirky as it is.
On the whole, I noticed you write cello parts that are in a very high register. Was that intentional? The treble register is a difficult one for a cellist. On the other side, you rarely venture into the higher register of the violin. I think a balance could be achieved. Musically speaking, I like your ideas very much, and my favourite mvmt is by far the second, the classical rondo being treated to only vaguely tonal harmonies and odd meters. A nice listen overall.
