Great progress already. The values and edges could have been closer in the first study and then right when I was about to compose those thoughts, you resolved them in the next. Very good work. The main area of value that could be even closer is from her waist to the top of her head. You went with a little bit different value range there so it is a little less luminous than the original. Aside from that nitpick it is looking really great.
This is going to be a very good thread. I look forward to the updates.
