Actually as irony would have it, the "less" detail on the face is what makes it feminine...the hair, on the other hand, was something I really wanted to get into and make as many tiny strands as possible to feather out the edges so it did not look like a black charcoal blob.
THANKS! With acrylic paints, I get a good effect with thick brush strokes but for realism and to approximate reality and be as close to the source material as possible, nothing beats sharpened charcoal pencils and a large enough work surface. (And of course with me, black and white is always good for realism. No color problems.
