After the tutorial I made some changes about aniamtic.
I remembered when I delete the part which she is writing music I was thinking about to put it at the end of the story but I didn’t do it. But seems this thing is quite important for this girl so I changed this part to emphasis it. The strings still are the symbol of music and I put some geometric shape on it and they will move with the music. I think the changing of this part makes it more smooth especially the connecting with the scene that she passes this therapy to the other.
Also this part. I add more expression on her face and finished the animation of this part.
