That really good! You seem to have great posture, good technique and great control of the bow. I even notice that you show expression with your body and in your face. It looks to me like you’re doing pretty good. The only thing you might want to work on is getting a more vibrant tone quality. To do this practice making your right arm and wrist just a little more relaxed. I saw a video here on Violin Tutor pro that showed how to do this in the air without touching the violin. Seriously, though, you show a lot of talent and promise!
