Sketched at the practice of YOB Orchestra

I did it last Saturday afternoon when my girls' orchestra were practicing. I was not very pleased with this sketch but I still wanted to leave a record of it. I was trying to capture the light but I failed in a way. I'm not sure but I think maybe it's its color that troubled me. I didn't like too much its tone and its value wasn't right either but the music was great. I believe the next one will be better. We'll see.
