Portrait of a young girl

I'm working on finishing this with watercolor and pen. It symbolizes growing up and the important relationships between old and young. Critiques are appreciated.

This pen sketch was based on a recent doodle. The songbird is clearing his throat, preparing for his musical performance.

This was inspired by portraits from the 1920's. I've read that some girls who adopted the flapper style only wore one earring because their hair covered the other ear.
