I haven't played this piece myself, and I've only got those half-crappy scores, so what I say might be wrong. But the first chords... I really don't like the heavy-light-thing only because there's a slur. The tradition is from the bowing, and no serious string playing would play it like that.
I like your tone, but I think you could change it a bit more. The left hand goes on, and the right has got this very sotto voce - which I like - but not all the time. Maybe it's just me, but I get kind of tired to listen to that for too long.
The part right before the the themes comes again (it ends in c-sharp major). You play it like nothing happens at all, and it gets kind of.. boring. At least do something with the colour.
And I think the ending is too ritenuto. Maybe it says molto rit., then I apologize, but it sounds too much for me.
Though, I really liked the second theme
