I am glad that you presented your finished work, it is really worth to do, it obviously took you a lot of time but when you pay attention to every single line and tone and values to make a realistic portrait it will be time consuming. The way you made the process photographs let us know how simple the sketch was and how it was turned into this magic final result. You showed that you are the person who goes to her aim and brings it to end, because I know sometimes people just leave it on some stage and it just stays unfinished. Wonderful portrait!
