Considering you're unscouted, and still working out your style and quirks of things...you did a pretty good job. I do agree with iRaider, the violin is abrasive as hell in the beginning, but other than that, the piece is pretty good. You do have a few sections where your instruments don't tie in well with each other and leave subtle skips/gaps.
No one's perfect and it takes a bit of fine tuning to get it just right! Keep practicing and working out those nasty flaws as they say! 4/5 for you! Keep it up!
