Opinion about Yiddish accent and articulation in singing

Hello!
I'm an actress and singer with Polish origins living in France. I started recently a project based on Mordechai Gebirtig songs, a project I wanted to do from a long time. Gebirtig is a polish yiddish poet killed in the Cracow gettho durng the war, he's the author of great yiddish songs, very popular before the War. Even if yiddish is close to my heart and I hopefuly have some intuition, I'm brand new in learning and what we calle auto-didacte. I would be very greatful to have your opinion about my yiddish accent and pronouncing in that songs that I've just registred in Rome.
