All right first thing, you have to EQ the highs, its way too piercing, its missing alot of mid and low in the mix to balance everything, the composition is fine you probably need to add some textures around it to make it fuller. And add a soundcloud, bandcamp, youtube link instead of downloading the file, its more convenient.

Also my feedback may seem brutal but don't be too offended by it, I went all in sine its unranked jam.

It's very nice; I may just think that the sound of the lead the violin is a little too strident and aggressive for a piece that is overall rather relaxing.
