Figure drawing encore

I am more satisfied with today's drawing than the previous one. I hadn't yet focused on a face in my drawings so instead of depicting her from the front or in full view I decided to crop it as a profile bust yet keeping the hand in there because I needed practice drawing hands as well. I'm pleased with how the face turned out. I tried to include all of the nuances I could capture. The hand was worked for a good while as well; it was difficult to proportion the different sections correctly. I think it is not 100% accurate yet but it's surely closer than the hand in the previous drawing.

I'm considering going back and filling in the chair with more detail..thoughts?
