Thanks for posting! You are doing a great job creating a good sound in many areas! I wasn’t able to see your left-hand clearly, but I could tell your intonation was good in most spots. What I would suggest to work on (and I give a lot of students this tip) is for you to use more index finger in the stroke. Right now what you are doing is using your upper arm and forearm to guide the stroke, which causes bow bounces in some areas and unnecessary accents. Here are the top 3 drills I would work on which should explain everything about the index finger as the motor of your bow stroke.
Once you start understanding more about how to use the index, you will be able to move the bow faster, and not feel like you are working so hard! Overall great job–thanks again for posting a video!
