Color Portrait #3

I really liked the original image of Marie done by a great photographer Lods Franck which I found at 500px: https://500px.com/photo/267114543/marie-by-lods-franck?ctx_page=3&from=user&user_id=12052365 
This time I tried to combine the photoreality with painterly look. I certainly underestimated the amount of details to draw and spent way too much time on it - much more then I expected at the beginning but I think the result is worth that. 
Drawing time: 18 hours
