I'm honestly thinking it's getting too busy, but when watching the movie, it does look that busy, however, I think my tracing, 'caused by the low quality cut and paste job made from the zoom-in on the picture in one of the movies is flawed.
I'll concentrate on the face and then see if I want to redo the perimeter details, the hair and the coat and collar later. The face is difficult enough... and I'm actually getting headaches now trying to trace this, as it's so fudged and obscured and unclear.
