Fantastic job! Thank you for sharing your first video with us! Even the best of us would rarely give a ‘flawless’ performance! Technically, I can suggest one thing for you to improve your playing. Your violin seems to be tilted quite a bit toward the right. I would like to see it angled back so it seems more flat. Part of that is just rolling from your waist, leaning back over the violin more. Let the violin elbow come under the violin. To test your violin posture, imagine your violin elbow being aligned with your big toe of the left foot, where most of your weight should be. Then, roll yourself a bit over, standing tall. Then some work on bow arm and you will have improved greatly! Cheers!
