Schubert? Not sure. Im weak on the classical compisers. Okay, two things. First, it's always amazing how children so young can play such complicated music. I'm struggling trying to get through "Joy Spring" on my trumpet. Second, we must find joy in playing music. I understand the game face before engaging the piano, but no smile afterward? Your musicianship will go to the next level if you put your joy into the music. After all, music is all about the expression of emotion of the composer and the performer. Well done. Keep practicing and never give up the music. You are a gift to the world. 🎉
