The violin composition is really nice.
I think this song would sound much better if you programmed the staccato note by note instead of using what sounds like action strings. Also, the song doesn't sound like it's being played in a real space; it seems to be mixed like its an electronic song.
I like what you were trying to do with this piece, but I think it needs more instruments for tension to be properly built. A brass ensemble would sound amazing here. I think more percussion is necessary as well.
With that said, I mostly enjoy the song if I listen to it casually. It would make good background music as is.
