This is beautiful! I only have one comment and it's the position of the bow on the violin, it should be back closer to her, not on the finger board as much. (Sorry, I've played the instrument for over 9 years... minor details bother me like that)
Thank you for the comment , and no, you're not bothering at all, cuz such a comment like that is what I really look into. My skill sucked at the time I painted this artwork and since I didn't study any reference seriously, such a fault was unavoidable. It's a great thing to receive a comment from a violin player like you for this pic .
I love how it looks like she's so absorbed in the music, and the texture of everything. You did a nice job on the leaves.
