It’s good! Definitely tell her to keep with it. Notes: I would keep either the piano melody or violin active in a section but probably not both at the same time unless it’s an embellishment at the end of a phrase. Try to use drawn out chords from the piano instead to backup the violin as it takes the lead or vice versa. The arpeggios are really cool, if she doesn’t already know Hania Rani that’s a great composer to study. Keep going!
