Very nice! You are getting a solid tone already so if you practice Suni’s suggestions for your bow arm, this will get even better! I would recommend practicing in the mirror and looking to see if your bow is lined up with the f holes and going straight. A tip for your left hand, try to keep all of your fingers very tall and bent. If you can keep your left hand pinky bent and on its tip, it will be all the more accurate!
Great job! I am a big fan of playing classical and fiddling! 🙂
