Good going with the drones as an intro.
I think maybe the strings still have that artificiality to them - one of my tricks with this is just to be mindful of my attack/release. I use a midi controller exclusively, so I'll hold one key down for a bit before releasing to give a more clean transition, with a slow attack on the strings, which can make for a smoother transition. Plus having the velocity control real time just helps get into the rhythm of it.
I think the composition maybe feels little "clicked in" with the midi? It still works well.
I think the way the violin is mixed/sounds doesn't quite fit the mix, and the sound of this particular violin is a bit harsh.
Great work overall!
