Your drawing is very good. It actually reminds me of this drawing in Milwaukee Museum. The art is "Nancy" by Chuck. This art is very detailed and you can even see her freckles. I wonder if you want to get to this level of details too. Just a thought.
I'm not so worried about details; I used to try to do an ultra realistic style but then I realized it wasn't nearly as fun as trying to make it more "creative" and different from a photograph. thanks for stopping by :)
