Girl's Portrait Study Phase IV

Today is definitely a Hair Day (good or bad? you decide).. I've added some gold in my girl's hair. Even she is a Blond now she is positively going to be a Cute Red Head. I've used wet-on -wet technique thinking that later I can touch the hair with the small (dry-on-wet) brush in order to define them. I know some artists that do not focus on defining hair and it does look great with the accent on the face and eyes, but for this portrait I think I will stick to my usual technique.
