Nice medium!
I know just how painful it can be to work with pastels at times! You did a wonder full job with this, reminds me of some of the more classical work I seen in several galleries, just lacking the classical background which in a way help reintroduces realism into art field with a fresh view.
The only nit picks I have are the lack of definition in the toes, hair and the some what odd shape of the shoulders, but as I've stated before I understand how difficult pastels you are using can be.
Odd as it may seem, I think if you keep at it, you may start to be this generations version of Norman Rockwell.
