Thank you Eiji for trying moving your body. Definitely better! It's important to do natually so it will take some time. (A few weeks) Relax your right hand more. When you go up... don't stop "still" too much, need to be loose more! アップストロークがちょっと固くなっています。ボクのデモヴィデオを何回も見てください。アップでストップした感じにならないでもっとフラフラの状態が理想です)Your muting finger got better! 1st finger mute on 6th string root chord. Your tone is great!
I think you can work on your head/body motion when you are listening music.

Tomo-sensei. Thank you very much for your advice. I will do this practice for a while to get used to it.
