My only nit is that the violin is the only instrument that I'm sure was miked by the OP - the other stuff could easily have been samples - in other words, the violin sticks out not because it's brilliantly miked and mixed, but because it sounds like it was obviously done in a different space to everything else. You can tell from the praise this one's getting that nobody minds that, but if I was mixing it, I'd be trying to get the violin track to match the backing more.
