Thanks for sharing and the post.

Even pros bow crookedly, the goal is to bow straighter and to control the direction of the bow. If you work at it enough you can even use the angle to play louder or softer, bring the bow closer of further from the strings.

Overall nice playing.

I would focus on intonation and with more emphasis on the octave higher part.

Use more right arm elbow as a start to getting a straighter bowing technique.

Your sound production is quite good but I wouldn't mind hearing more dynamics, as you did at the end of Sad Romance but getting softer. It adds a lot. Music without dynamics is like a picture without contrast or colors.

You get a critique video badge too. 🙂
