"Yellow Calla with Cup"

This is not the final version of this pastel. It is a work in progress. As I add more pastel and make drawing corrections, I will post those as well. This is an 8" X 10" pastel on dark blue Canson paper. So far this is done from life. I am trying to stay with my pastels longer than usual and when the going gets rough...I am trying not to move on to another painting but stick with it and resolve the hard problems. Any feedback would be appreciated.
