Nice piece. Yeah, the strings seem to be the biggest issue. I did notice "pitch wheel" action. That something (to me unexpected). Did the bow slip out of someone's hand?
That first part I expected that partial quartal voicing arp to finish (theory humor).
The piano was nice, but the reverb was a bit much (to me) or was it the patch used (with the preset). Is it supposed to be in a concert hall?
Nice dialogue among the strings, but tone the "egos" a tiny bit.
Again, nice piece and I hope his gets you into the conservatory.
