Hello Yinmui, your tone has definitely improved compared to your first post!! Great job! And a great piece too!
If I may give you one tip, try to relax the fingers of your right hand. Definitely try to keep the pinky finger curved. A relaxed right hand will give you an even better tone.
Something that helps me to relax while I play is smiling. When you smile, your whole body relaxes. 😉 For example, look at David Garrett in this video. He smiles almost all the time and his arms, his neck, his entire body is so relaxed. https://www.youtube.com/watch?v=n-2tbvRsCUA
